This document describes a proposed concept-based mining model that aims to improve document clustering and information retrieval by extracting concepts and semantic relationships rather than just keywords. The model uses natural language processing techniques like part-of-speech tagging and parsing to extract concepts from text. It represents concepts and their relationships in a semantic network and clusters documents based on conceptual similarity rather than term frequency. The model is evaluated using singular value decomposition to increase the precision of key term and phrase extraction.

CONTEXT-AWARE CLUSTERING USING GLOVE AND K-MEANSijseajournal
ABSTRACT
In this paper we propose a novel method to cluster categorical data while retaining their context. Typically, clustering is performed on numerical data. However it is often useful to cluster categorical data as well, especially when dealing with data in real-world contexts. Several methods exist which can cluster categorical data, but our approach is unique in that we use recent text-processing and machine learning advancements like GloVe and t- SNE to develop a a context-aware clustering approach (using pre-trained
word embeddings). We encode words or categorical data into numerical, context-aware, vectors that we use to cluster the data points using common clustering algorithms like K-means.
EXPERT OPINION AND COHERENCE BASED TOPIC MODELINGijnlc
In this paper, we propose a novel algorithm that rearrange the topic assignment results obtained from topic
modeling algorithms, including NMF and LDA. The effectiveness of the algorithm is measured by how much
the results conform to expert opinion, which is a data structure called TDAG that we defined to represent the
probability that a pair of highly correlated words appear together. In order to make sure that the internal
structure does not get changed too much from the rearrangement, coherence, which is a well known metric
for measuring the effectiveness of topic modeling, is used to control the balance of the internal structure.
We developed two ways to systematically obtain the expert opinion from data, depending on whether the
data has relevant expert writing or not. The final algorithm which takes into account both coherence and
expert opinion is presented. Finally we compare amount of adjustments needed to be done for each topic
modeling method, NMF and LDA.

The document proposes a method called Page Count and Snippets Method (PCSM) to estimate semantic similarity between words using information from web search engines. PCSM uses both page counts and lexical patterns extracted from snippets to measure semantic similarity. It defines five page count-based concurrence measures and extracts lexical patterns from snippets to identify semantic relations between words. Support vector machine is used to integrate the similarity scores from page counts and snippet methods. The method is evaluated on benchmark datasets and shows improved correlation compared to existing methods.

Text clustering plays a key role in navigation and browsing process. For an efficient text clustering, the large amount of information is grouped into meaningful clusters. Multiple text clustering techniques do not address the issues such as, high time and space complexity, inability to understand the relational and contextual attributes of the word, less robustness, risks related to privacy exposure, etc. To address these issues, an efficient text based clustering framework is proposed. The Reuters dataset is chosen as the input dataset. Once the input dataset is preprocessed, the similarity between the words are computed using the cosine similarity. The similarities between the components are compared and the vector data is created. From the vector data the clustering particle is computed. To optimize the clustering results, mutation is applied to the vector data. The performance the proposed text based clustering framework is analyzed using the metrics such as Mean Square Error (MSE), Peak Signal Noise Ratio (PSNR) and Processing time. From the experimental results, it is found that, the proposed text based clustering framework produced optimal MSE, PSNR and processing time when compared to the existing Fuzzy C-Means (FCM) and Pairwise Random Swap (PRS) methods.

An efficient concept based mining model for enhancing text clustering(synopsis)Mumbai Academisc
The document proposes a new concept-based mining model for text clustering that analyzes terms at the sentence, document, and corpus levels to better capture semantics. It introduces measures for concept analysis at each level and a concept-based similarity measure. Experiments on various datasets show the approach substantially improves clustering quality over traditional frequency-based analyses.
In this paper we tried to correlate text sequences those provides common topics for semantic clues. We propose a two step method for asynchronous text mining. Step one check for the common topics in the sequences and isolates these with their timestamps. Step two takes the topic and tries to give the timestamp of the text document. After multiple repetitions of step two, we could give optimum result.
An Efficient Semantic Relation Extraction Method For Arabic Texts Based On Si...CSCJournals
The document presents a method for extracting semantic relations between concepts in Arabic texts. It constructs context vectors for concepts based on their co-occurrence with other concepts. It then uses several semantic similarity measures (Cosine, Jaccard, Lin) to calculate similarity scores between candidate concept vectors and seed concept vectors. Relations are extracted between candidates and seeds if their similarity score is above the average threshold for that seed. The method was evaluated on an Arabic corpus and achieved a precision of 83-85% for relation extraction, showing it is an effective unsupervised approach for extracting relations to construct Arabic ontologies.
This document describes a method for sentence similarity based text summarization using clusters. It involves preprocessing text, extracting primitives from sentences, linking primitives, computing sentence similarity, merging similarity values, clustering similar sentences, and extracting a representative sentence from each cluster to generate a summary. Key steps include identifying common elements (primitives) between sentences, representing sentences as vectors of primitives, computing similarity based on shared primitives, clustering similar sentences, pruning clusters to remove dissimilar sentences, ranking clusters by importance, and selecting a representative sentence from each cluster for the summary. The goal is to automatically generate a short summary that captures the essential information from a collection of documents or text on the same topic.

In this paper we present a novel approach to semi-automatically learn concept hierarchies from natural
language requirements of the automotive industry. The approach is based on the distributional hypothesis
and the special characteristics of domain-specific German compounds. We extract taxonomies by using
clustering techniques in combination with general thesauri. Such a taxonomy can be used to support
requirements engineering in early stages by providing a common system understanding and an agreedupon
terminology. This work is part of an ontology-driven requirements engineering process, which builds
on top of the taxonomy. Evaluation shows that this taxonomy extraction approach outperforms common
hierarchical clustering techniques.
Order out of Chaos: Construction of Knowledge Models from PDF TextbooksIsaac Alpizar-Chacon
Textbooks are educational documents created, structured and formatted by domain experts with the main purpose to explain the knowledge in the domain to a novice. Authors use their understanding of the domain when structuring and formatting the content of a textbook to facilitate this explanation. As a result, the formatting and structural elements of textbooks carry the elements of domain knowledge implicitly encoded by their authors. Our paper presents an extendable approach towards automated extraction of this knowledge from textbooks taking into account their formatting rules and internal structure. We focus on PDF as the most common textbook representation format; however, the overall method is applicable to other formats as well. The evaluation experiments examine the accuracy of the approach, as well as the pragmatic quality of the obtained knowledge models using one of their possible applications --- semantic linking of textbooks in the same domain. The results indicate high accuracy of model construction on symbolic, syntactic and structural levels across textbooks and domains, and demonstrate the added value of the extracted models on the semantic level.
Presented at Document Engineering 2020
This document summarizes a research paper that proposes a new representation for relational learning that allows the use of propositional learning algorithms. The paper argues that traditional inductive logic programming (ILP) approaches have limitations like intractability and inefficiency. It presents a representation using a restricted first-order logic and graph structures that can be converted to propositions, enabling the use of propositional and probabilistic learning algorithms. An information extraction system using this approach achieved better performance than other ILP-based systems. The paper contributes a new paradigm for relational learning but did not fully analyze the contributions of its two-stage architecture.
Integrating Textbooks with Smart Interactive Content for Learning ProgrammingIsaac Alpizar-Chacon
Online textbooks with interactive content emerged as a popular medium for learning programming and other computer science topics. While the textbook component supports acquisition of programming concepts by reading, various types of ``smart'' interactive learning content such as worked examples, code animations, Parson's puzzles, and coding problems allow students to immediately practice and master the newly learned concepts. This paper attempts to automate the time-consuming manual process of augmenting textbooks with ``smart'' interactive content. We introduce an ontology-based approach that can link fragment of text with ``smart'' content activities, demonstrate its application to two practical linking cases, and present the results of its pilot evaluation.
The document summarizes research on multi-document summarization using EM clustering. It begins with an introduction to the topic and issues with existing techniques. It then proposes using Expectation-Maximization (EM) clustering to identify clusters, which improves over other methods by identifying latent semantic variables between sentences. The architecture involves preprocessing, EM clustering, mutual reinforcement ranking algorithms RARP and RDRP, summarization, and post-processing. Experimental results on DUC2007 data show EM clustering identifies more clusters and sentences than affinity propagation clustering. The technique aims to improve summarization accuracy by better capturing semantic relationships between sentences.
SEMANTICS GRAPH MINING FOR TOPIC DISCOVERY AND WORD ASSOCIATIONSIJDKP
Big Data creates many challenges for data mining experts, in particular in getting meanings of text data. It is beneficial for text mining to build a bridge between word embedding process and graph capacity to connect the dots and represent complex correlations between entities. In this study we examine processes of building a semantic graph model to determine word associations and discover document topics. We introduce a novel Word2Vec2Graph model that is built on top of Word2Vec word embedding model. We demonstrate how this model can be used to analyze long documents, get unexpected word associations and uncover document topics. To validate topic discovery method we transfer words to vectors and vectors to images and use CNN deep learning image classification.
This document summarizes a survey on string similarity matching search techniques. It discusses how string similarity matching is used to find relevant information in text collections.

It analyzes techniques like pattern matching, threshold-based joins, and vector representations. The goal is to present an overview of the field and compare algorithm performance for similarity searches.

The document discusses a study that trained a GPT-2 model to generate contextual definitions for words based on the provided context. The model was trained on a new dataset containing definition and context pairs from various sources. It was evaluated through surveys where human raters assessed definitions generated by the model for short and long contexts, as well as real human-generated definitions. The results found that while the model performed significantly better at generating definitions for short contexts compared to long ones, human-generated definitions were still significantly more accurate. Areas for improvement included reducing fluctuations depending on context and better interpreting some contexts.

Feature selection, optimization and clustering strategies of text documentsIJECEIAES
Clustering is one of the most researched areas of data mining applications in the contemporary literature. The need for efficient clustering is observed across wide sectors including consumer segmentation, categorization, shared filtering, document management, and indexing. The research of clustering task is to be performed prior to its adaptation in the text environment. Conventional approaches typically emphasized on the quantitative information where the selected features are numbers. Efforts also have been put forward for achieving efficient clustering in the context of categorical information where the selected features can assume nominal values. This manuscript presents an in-depth analysis of challenges of clustering in the text environment. Further, this paper also details prominent models proposed for clustering along with the pros and cons of each model. In addition, it also focuses on various latest developments in the clustering task in the social network and associated environments.
This document presents a general framework for building classifiers and clustering models using hidden topics to deal with short and sparse text data. It analyzes hidden topics from a large universal dataset using LDA. These topics are then used to enrich both the training data and new short text data by combining them with the topic distributions. This helps reduce data sparseness and improves classification and clustering accuracy for short texts like web snippets. The framework is also applied to contextual advertising by matching web pages and ads based on their hidden topic similarity.
AN EFFICIENT APPROACH FOR SEMANTICALLYENHANCED DOCUMENT CLUSTERING BY USING W...ijaia
This document presents a new approach to improve document clustering by exploiting the semantic relationships between terms contained in Wikipedia. The approach first maps terms within documents to corresponding Wikipedia concepts. It then calculates the semantic similarity between terms using Wikipedia's link structure. The document vectors are adjusted so that semantically related terms gain more weight. The approach differs from previous work by using a well-known measure of semantic similarity based on Normalized Google Distance, and by applying phrase extraction to more efficiently map terms to Wikipedia concepts. An evaluation on two datasets found the approach improved clustering results over other state-of-the-art methods.
An efficient approach for semantically enhanced document clustering by using ...ijaia
Traditional techniques of document clustering do not consider the semantic relationships between words
when assigning documents to clusters. For instance, if two documents talking about the same topic do that
using different words (which may be synonyms or semantically associated), these techniques may assign
documents to different clusters. Previous research has approached this problem by enriching the document
representation with the background knowledge in an ontology. This paper presents a new approach to
enhance document clustering by exploiting the semantic knowledge contained in Wikipedia. We first map
terms within documents to their corresponding Wikipedia concepts. Then, similarity between each pair of
terms is calculated by using the Wikipedia's link structure. The document’s vector representation is then
adjusted so that terms that are semantically related gain more weight. Our approach differs from related
efforts in two aspects: first, unlink others who built their own methods of measuring similarity through the
Wikipedia categories; our approach uses a similarity measure that is modelled after the Normalized
Google Distance which is a well-known and low-cost method of measuring term similarity. Second, it is
more time efficient as it applies an algorithm for phrase extraction from documents prior to matching terms
with Wikipedia. Our approach was evaluated by being compared with different methods from the state of
the art on two different datasets. Empirical results showed that our approach improved the clustering
results as compared to other approaches.
Improving Text Categorization with Semantic Knowledge in Wikipediachjshan
Text categorization, especially short text categorization, is a difficult and challenging task since the text data is sparse and multidimensional. In traditional text classification methods, document texts are represented with “Bag of Words (BOW)” text representation schema, which is based on word co-occurrence and has many limitations. In this paper, we mapped document texts to Wikipedia concepts and used the Wikipedia-concept-based document representation method to take the place of traditional BOW model for text classification. In order to overcome the weakness of ignoring the semantic relationships among terms in document representation model and utilize rich semantic knowledge in Wikipedia, we constructed a semantic matrix to enrich Wikipedia-concept-based document representation. Experimental evaluation on five real datasets of long and short text shows that our approach outperforms the traditional BOW method.
THE ABILITY OF WORD EMBEDDINGS TO CAPTURE WORD SIMILARITIESkevig
Distributed language representation has become the most widely used technique for language representation in various natural language processing tasks. Most of the natural language processing models that are based on deep learning techniques use already pre-trained distributed word representations, commonly called word embeddings. Determining the most qualitative word embeddings is of crucial importance for such models. However, selecting the appropriate word embeddings is a perplexing task since the projected embedding space is not intuitive to humans. In this paper, we explore different approaches for creating distributed word representations. We perform an intrinsic evaluation of several state-of-the-art word embedding methods. Their performance on capturing word similarities is analysed with existing benchmark datasets for word pairs similarities. The research in this paper conducts a correlation analysis between ground truth word similarities and similarities obtained by different word embedding methods.

Traditional techniques of document clustering do not consider the semantic relationships between words
when assigning documents to clusters. For instance, if two documents talking about the same topic do that
using different words (which may be synonyms or semantically associated), these techniques may assign
documents to different clusters. Previous research has approached this problem by enriching the document
representation with the background knowledge in an ontology. This paper presents a new approach to
enhance document clustering by exploiting the semantic knowledge contained in Wikipedia. We first map
terms within documents to their corresponding Wikipedia concepts. Then, similarity between each pair of
terms is calculated by using the Wikipedia's link structure. The document’s vector representation is then
adjusted so that terms that are semantically related gain more weight. Our approach differs from related
efforts in two aspects: first, unlink others who built their own methods of measuring similarity through the
Wikipedia categories; our approach uses a similarity measure that is modelled after the Normalized
Google Distance which is a well-known and low-cost method of measuring term similarity. Second, it is
more time efficient as it applies an algorithm for phrase extraction from documents prior to matching terms
with Wikipedia. Our approach was evaluated by being compared with different methods from the state of
the art on two different datasets. Empirical results showed that our approach improved the clustering
results as compared to other approaches.
Improving Text Categorization with Semantic Knowledge in Wikipediachjshan
Text categorization, especially short text categorization, is a difficult and challenging task since the text data is sparse and multidimensional. In traditional text classification methods, document texts are represented with “Bag of Words (BOW)” text representation schema, which is based on word co-occurrence and has many limitations. In this paper, we mapped document texts to Wikipedia concepts and used the Wikipedia-concept-based document representation method to take the place of traditional BOW model for text classification. In order to overcome the weakness of ignoring the semantic relationships among terms in document representation model and utilize rich semantic knowledge in Wikipedia, we constructed a semantic matrix to enrich Wikipedia-concept-based document representation. Experimental evaluation on five real datasets of long and short text shows that our approach outperforms the traditional BOW method.
THE ABILITY OF WORD EMBEDDINGS TO CAPTURE WORD SIMILARITIESkevig
Distributed language representation has become the most widely used technique for language representation in various natural language processing tasks. Most of the natural language processing models that are based on deep learning techniques use already pre-trained distributed word representations, commonly called word embeddings. Determining the most qualitative word embeddings is of crucial importance for such models. However, selecting the appropriate word embeddings is a perplexing task since the projected embedding space is not intuitive to humans. In this paper, we explore different approaches for creating distributed word representations. We perform an intrinsic evaluation of several state-of-the-art word embedding methods. Their performance on capturing word similarities is analysed with existing benchmark datasets for word pairs similarities. The research in this paper conducts a correlation analysis between ground truth word similarities and similarities obtained by different word embedding methods.

A comparative analysis of particle swarm optimization and k means algorithm f...ijnlc
The volume of digitized text documents on the web have been increasing rapidly. As there is huge collection
of data on the web there is a need for grouping(clustering) the documents into clusters for speedy
information retrieval. Clustering of documents is collection of documents into groups such that the
documents within each group are similar to each other and not to documents of other groups. Quality of
clustering result depends greatly on the representation of text and the clustering algorithm. This paper
presents a comparative analysis of three algorithms namely K-means, Particle swarm Optimization (PSO)
and hybrid PSO+K-means algorithm for clustering of text documents using WordNet. The common way of
representing a text document is bag of terms. The bag of terms representation is often unsatisfactory as it
does not exploit the semantics. In this paper, texts are represented in terms of synsets corresponding to a
word. Bag of terms data representation of text is thus enriched with synonyms from WordNet. K-means,
Particle Swarm Optimization (PSO) and hybrid PSO+K-means algorithms are applied for clustering of
text in Nepali language. Experimental evaluation is performed by using intra cluster similarity and inter
cluster similarity.
Correlation Preserving Indexing Based Text ClusteringIOSR Journals
This document discusses a correlation preserving indexing (CPI) based text clustering method. CPI aims to find a low dimensional semantic subspace that maximizes correlation between similar documents while minimizing correlation between dissimilar documents. It is different from other methods like LSI and LPI that use Euclidean distance. The document outlines the CPI method and evaluates it on document clustering tasks, showing it doubles the accuracy of previous correlation-based methods. Hierarchical clustering algorithms are also discussed and compared to CPI in terms of evaluation metrics.
Research on ontology based information retrieval techniquesKausar Mukadam
The document summarizes and compares three novel ontology-based information retrieval techniques. It discusses a technique for retrieving information in the domain of Traditional Chinese Medicine that uses an ontology to represent concepts and measures concept similarity to sort search results. It also describes a framework for semantic indexing and querying that uses an ontology and entity-attribute-value model to improve scalability, usability, and retrieval performance for transport systems. Additionally, it outlines a semantic extension retrieval model that uses ontology annotation and semantic extension of queries to address limitations of keyword-based search. The techniques are evaluated based on precision and recall measures to analyze their effectiveness compared to traditional methods.
ONTOLOGY INTEGRATION APPROACHES AND ITS IMPACT ON TEXT CATEGORIZATIONIJDKP
This article will introduce some approaches for improving text categorization models by integrating
previously imported ontologies. From the Reuters Corpus Volume I (RCV1) dataset, some categories very

Nowadays, document clustering is considered as a da
ta intensive task due to the dramatic, fast increas
e in
the number of available documents. Nevertheless, th
e features that represent those documents are also
too
large. The most common method for representing docu
ments is the vector space model, which represents
document features as a bag of words and does not re
present semantic relations between words. In this
paper we introduce a distributed implementation for
the bisecting k-means using MapReduce programming
model. The aim behind our proposed implementation i
s to solve the problem of clustering intensive data
documents. In addition, we propose integrating the
WordNet ontology with bisecting k-means in order to
utilize the semantic relations between words to enh
ance document clustering results. Our presented
experimental results show that using lexical catego
ries for nouns only enhances internal evaluation
measures of document clustering; and decreases the
documents features from thousands to tens features.

A survey on phrase structure learning methods for text classificationijnlc
Text classification is a task of automatic classification of text into one of the predefined categories. The
problem of text classification has been widely studied in different communities like natural language
processing, data mining and information retrieval. Text classification is an important constituent in many
information management tasks like topic identification, spam filtering, email routing, language
identification, genre classification, readability assessment etc. The performance of text classification
improves notably when phrase patterns are used. The use of phrase patterns helps in capturing non-local
behaviours and thus helps in the improvement of text classification task. Phrase structure extraction is the
first step to continue with the phrase pattern identification. In this survey, detailed study of phrase structure
learning methods have been carried out. This will enable future work in several NLP tasks, which uses
syntactic information from phrase structure like grammar checkers, question answering, information
extraction, machine translation, text classification. The paper also provides different levels of classification
and detailed comparison of the phrase structure learning methods.
LARQS: AN ANALOGICAL REASONING EVALUATION DATASET FOR LEGAL WORD EMBEDDINGkevig
Applying natural language processing-related algorithms is currently a popular project in legal
applications, for instance, document classification of legal documents, contract review and machine
translation. Using the above machine learning algorithms, all need to encode the words in the document in
the form of vectors. The word embedding model is a modern distributed word representation approach and
the most common unsupervised word encoding method. It facilitates subjecting other algorithms and
subsequently performing the downstream tasks of natural language processing vis-à-vis. The most common
and practical approach of accuracy evaluation with the word embedding model uses a benchmark set with
linguistic rules or the relationship between words to perform analogy reasoning via algebraic calculation.
This paper proposes establishing a 1,256 Legal Analogical Reasoning Questions Set (LARQS) from the
2,388 Chinese Codex corpus using five kinds of legal relations, which are then used to evaluate the
accuracy of the Chinese word embedding model. Moreover, we discovered that legal relations might be
ubiquitous in the word embedding model.

IRJET- Short-Text Semantic Similarity using Glove Word EmbeddingIRJET Journal
The document describes a study that uses GloVe word embeddings to measure semantic similarity between short texts. GloVe is an unsupervised learning algorithm for obtaining vector representations of words. The study trains GloVe word embeddings on a large corpus, then uses the embeddings to encode short texts and calculate their semantic similarity, comparing the accuracy to methods that use Word2Vec embeddings. It aims to show that GloVe embeddings may provide better performance for short text semantic similarity tasks.
Abstract: Traditional approaches for document classification need data which is labelled for the construction reliable classifiers which are even accurate. Unfortunately, data which is already labelled are rarely available, and often too costly to obtain. For the given learning task for which data which is trained is unavailable, abundant labelled data may be there for a different and related domain. One would like to use the related labelled data as auxiliary information to accomplish the classification task in the target domain. Recently, the paradigm of transfer learning has been introduced to enable effective learning strategies when auxiliary data obey a different probability distribution. A co-clustering based classification algorithm has been previously proposed to tackle cross-domain text classification. In this work, we extend the idea underlying this approach by making the latent semantic relationship between the two domains explicit. This goal is achieved with the use of Wikipedia. As a result, the pathway that allows propagating labels between the two domains not only captures common words, but also semantic concepts based on the content of documents. We empirically demonstrate the efficacy of our semantic-based approach to cross-domain classification using a variety of real data.Keywords: Classification, Clustering, Cross-domain Text Classification, Co-clustering, Labelled data, Traditional Approaches.

DOCUMENT SUMMARIZATION IN KANNADA USING KEYWORD EXTRACTION cscpconf
The internet has caused a humongous growth in the amount of data available to the common
man. Summaries of documents can help find the right information and are particularly effective
when the document base is very large. Keywords are closely associated to a document as they
reflect the document's content and act as indexes for the given document. In this work, we
present a method to produce extractive summaries of documents in the Kannada language. The
algorithm extracts key words from pre-categorized Kannada documents collected from online
resources. We combine GSS (Galavotti, Sebastiani, Simi) coefficients and IDF (Inverse
Document Frequency) methods along with TF (Term Frequency) for extracting key words and
later use these for summarization. In the current implementation a document from a given category is selected from our database and depending on the number of sentences given by theuser, a summary is generated.
Document Classification Using KNN with Fuzzy Bags of Word Representationsuthi
Abstract — Text classification is used to classify the documents depending on the words, phrases and word combinations according to the declared syntaxes. There are many applications that are using text classification such as artificial intelligence, to maintain the data according to the category and in many other. Some keywords which are called topics are selected to classify the given document. Using these Topics the main idea of the document can be identified. Selecting the Topics is an important task to classify the document according to the category. In this proposed system keywords are extracted from documents using TF-IDF and Word Net. TF-IDF algorithm is mainly used to select the important words by which document can be classified. Word Net is mainly used to find similarity between these candidate words. The words which are having the maximum similarity are considered as Topics(keywords). In this experiment we used TF-IDF model to find the similar words so that to classify the document. Decision tree algorithm gives the better accuracy for text classification when compared to other algorithms fuzzy system to classify text written in natural language according to topic. It is necessary to use a fuzzy classifier for this task, due to the fact that a given text can cover several topics with different degrees. In this context, traditional classifiers are inappropriate, as they attempt to sort each text in a single class in a winner-takes-all fashion. The classifier we proposeautomatically learns its fuzzy rules from training examples. We have applied it to classify news articles, and the results we obtained are promising. The dimensionality of a vector is very important in text classification. We can decrease this dimensionality by using clustering based on fuzzy logic. Depending on the similarity we can classify the document and thus they can be formed into clusters according to their Topics. After formation of clusters one can easily access the documents and save the documents very easily. In this we can find the similarity and summarize the words called Topics which can be used to classify the Documents.
This document proposes using an enhanced suffix tree approach to measure semantic similarity between multiple documents. It involves preprocessing documents by removing stop words, special characters, and converting to lowercase. Phrases are extracted and used to construct a suffix tree, where internal nodes represent phrases shared across documents. Term frequency-inverse document frequency (tf-idf) is used to calculate weights for internal nodes. Cosine, Dice, and Hellinger similarity measures are then applied to calculate pairwise similarities between documents based on the weighted internal nodes. The approach aims to efficiently and accurately measure semantic similarity between documents.

This document discusses efficient rendezvous algorithms for wireless sensor networks with mobile base stations. It proposes an approach where select sensor nodes act as rendezvous points, buffering and aggregating data from other sensors. These rendezvous points then transfer the collected data to the base station when it arrives, combining the advantages of controlled mobility and in-network caching. Algorithms are presented for rendezvous design with mobile base stations having variable or fixed tracks. Both theoretical analysis and simulations validate that this approach can achieve a good balance between energy savings and reduced data collection latency in the network.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

A Context based Word Indexing Model for Document
Summarization
Abstract
Existing models for document summarization mostly use the similarity
between sentences in the document to extract most salient sentences. The
documents as well as the sentences are indexed using traditional term indexing
measures, which do not take the context into consideration. Therefore, the sentence
similarity values remain independent of the context. In this paper, we propose a
context sensitive document indexing model based on the Bernoulli model of
randomness. The Bernoulli model of randomness has been used to find the
probability of the co-occurrences of two terms in a large corpora. A new approach
using the lexical association between terms to give a context sensitive weight to the
document terms has been proposed. The resulting indexing weights are used to
compute the sentence similarity matrix. The proposed sentence similarity measure
has been used with the baseline graph-based ranking models for sentence
extraction. Experiments have been conducted over the benchmark DUC datasets
and it has been shown that the proposed Bernoulli based sentence similarity model
provides consistent improvements over the baseline IntraLink and UniformLink
