The document proposes an algorithm to calculate the relevance of documents returned in response to user queries in information retrieval systems. It is based on classical similarity formulas like cosine, Jaccard, and dice that calculate similarity between document and query vectors. The algorithm aims to integrate user search preferences as a variable in determining document relevance, as classic models do not account for this. It uses text and web mining techniques to process user query and document metadata.

An effective pre processing algorithm for information retrieval systemsijdms
The Internet is probably the most successful distributed computing system ever. However, our capabilities
for data querying and manipulation on the internet are primordial at best. The user expectations are
enhancing over the period of time along with increased amount of operational data past few decades. The
data-user expects more deep, exact, and detailed results. Result retrieval for the user query is always
relative o the pattern of data storage and index. In Information retrieval systems, tokenization is an
integrals part whose prime objective is to identifying the token and their count. In this paper, we have
proposed an effective tokenization approach which is based on training vector and result shows that
efficiency/ effectiveness of proposed algorithm. Tokenization on documents helps to satisfy user’s
information need more precisely and reduced search sharply, is believed to be a part of information
retrieval. Pre-processing of input document is an integral part of Tokenization, which involves preprocessing
of documents and generates its respective tokens which is the basis of these tokens probabilistic
IR generate its scoring and gives reduced search space. The comparative analysis is based on the two
parameters; Number of Token generated, Pre-processing time.
Data mining , knowledge discovery is the process
of analyzing data from different perspectives and summarizing it
into useful information - information that can be used to increase
revenue, cuts costs, or both. Data mining software is one of a
number of analytical tools for analyzing data. It allows users to
analyze data from many different dimensions or angles, categorize
it, and summarize the relationships identified. Technically, data
mining is the process of finding correlations or patterns among
dozens of fields in large relational databases. The goal of
clustering is to determine the intrinsic grouping in a set of
unlabeled data. But how to decide what constitutes a good
clustering? It can be shown that there is no absolute “best”
criterion which would be independent of the final aim of the
clustering. Consequently, it is the user which must supply this
criterion, in such a way that the result of the clustering will suit
their needs.
For instance, we could be interested in finding
representatives for homogeneous groups (data reduction), in
finding “natural clusters” and describe their unknown properties
(“natural” data types), in finding useful and suitable groupings
(“useful” data classes) or in finding unusual data objects (outlier
detection).Of late, clustering techniques have been applied in the
areas which involve browsing the gathered data or in categorizing
the outcome provided by the search engines for the reply to the
query raised by the users. In this paper, we are providing a
comprehensive survey over the document clustering.
Activity Context Modeling in Context-AwareEditor IJCATR
The explosion of mobile devices has fuelled the advancement of pervasive computing to provide personal assistance in this
information-driven world. Pervasive computing takes advantage of context-aware computing to track, use and adapt to contextual
information. The context that has attracted the attention of many researchers is the activity context. There are six major techniques that
are used to model activity context. These techniques are key-value, logic-based, ontology-based, object-oriented, mark-up schemes and
graphical. This paper analyses these techniques in detail by describing how each technique is implemented while reviewing their pros
and cons. The paper ends with a hybrid modeling method that fits heterogeneous environment while considering the entire of modeling
through data acquisition and utilization stages. The modeling stages of activity context are data sensation, data abstraction and
reasoning and planning. The work revealed that mark-up schemes and object-oriented are best applicable at the data sensation stage.
Key-value and object-oriented techniques fairly support data abstraction stage whereas the logic-based and ontology-based techniques
are the ideal techniques for reasoning and planning stage. In a distributed system, mark-up schemes are very useful in data
communication over a network and graphical technique should be used when saving context data into database.
Clustering of Deep WebPages: A Comparative Studyijcsit
The internethas massive amount of information. This information is stored in the form of zillions of
webpages. The information that can be retrieved by search engines is huge, and this information constitutes
the ‘surface web’.But the remaining information, which is not indexed by search engines – the ‘deep web’,
is much bigger in size than the ‘surface web’, and remains unexploited yet.
Several machine learning techniques have been commonly employed to access deep web content. Under
machine learning, topic models provide a simple way to analyze large volumes of unlabeled text. A ‘topic’is
a cluster of words that frequently occur together and topic models can connect words with similar
meanings and distinguish between words with multiple meanings. In this paper, we cluster deep web
databases employing several methods, and then perform a comparative study. In the first method, we apply
Latent Semantic Analysis (LSA) over the dataset. In the second method, we use a generative probabilistic
model called Latent Dirichlet Allocation(LDA) for modeling content representative of deep web
databases.Both these techniques are implemented after preprocessing the set of web pages to extract page
contents and form contents.Further, we propose another version of Latent Dirichlet Allocation (LDA) to the
dataset. Experimental results show that the proposed method outperforms the existing clustering methods.

EFFICIENT SCHEMA BASED KEYWORD SEARCH IN RELATIONAL DATABASESIJCSEIT Journal
Keyword search in relational databases allows user to search information without knowing database
schema and using structural query language (SQL). In this paper, we address the problem of generating
and evaluating candidate networks. In candidate network generation, the overhead is caused by raising the
number of joining tuples for the size of minimal candidate network. To reduce overhead, we propose
candidate network generation algorithms to generate a minimum number of joining tuples according to the
maximum number of tuple set. We first generate a set of joining tuples, candidate networks (CNs). It is
difficult to obtain an optimal query processing plan during generating a number of joins. We also develop a
dynamic CN evaluation algorithm (D_CNEval) to generate connected tuple trees (CTTs) by reducing the
size of intermediate joining results. The performance evaluation of the proposed algorithms is conducted
on IMDB and DBLP datasets and also compared with existing algorithms.
Performance Evaluation of Query Processing Techniques in Information Retrievalidescitation
The first element of the search process is the query.
The user query being on an average restricted to two or three
keywords makes the query ambiguous to the search engine.
Given the user query, the goal of an Information Retrieval
[IR] system is to retrieve information which might be useful
or relevant to the information need of the user. Hence, the
query processing plays an important role in IR system.
The query processing can be divided into four categories
i.e. query expansion, query optimization, query classification and
query parsing. In this paper an attempt is made to evaluate the
performance of query processing algorithms in each of the
category. The evaluation was based on dataset as specified by
Forum for Information Retrieval [FIRE15]. The criteria used
for evaluation are precision and relative recall. The analysis is
based on the importance of each step in query processing. The
experimental results show that the significance of each step
in query processing and also the relevance of web semantics
and spelling correction in the user query.

An efficient information retrieval ontology system based indexing for contexteSAT Journals
Abstract Many of the research or development projects are constructed and vast type of artifacts are released such as article, patent, report of research, conference papers, journal papers, experimental data and so on. The searching of the particular context through the keywords from the repository is not an easy task because the earliest system the problem of huge recalls with low precision. This paper challenges to construct a search algorithm based on the ontology to retrieve the relevant contexts. Ontology's are great knowledge of retrieving the context. In this paper, we utilize the WordNet ontology to retrieve the relevant contexts from the document repository. It is very difficult to retrieve the relevant context in its original format since we use the pre-processing step, which helps to retrieve context. The pre-processing step includes two major steps first one is stop word removal and the second one is stemming process. The outcome of the pre-processing step is indexing consist of important keywords and their corresponding keywords. When the user enter the keyword to the system, the ontology makes the several steps to make the refine keywords. Finally, the refine keywords are matched with index and relevant contexts are retrieved. The experimentation process is carried out with the help of different set of contexts to achieve the results and the performance analysis of the proposed approach is estimated by the evaluation metrics like precision, recall and F-measure. Keywords— Ontologies; WordNet; contexts; stemming; indexing.
UML MODELING AND SYSTEM ARCHITECTURE FOR AGENT BASED INFORMATION RETRIEVALijcsit
In this current technological era, there is an enormous increase in the information available on web and
also in the online databases. This information abundance increases the complexity of finding relevant
information. To solve such challenges, there is a need for improved and intelligent systems for efficient
search and retrieval. Intelligent Agents can be used for better search and information retrieval in a
document collection. The information required by a user is scattered in a large number of databases. In this
paper, the object oriented modeling for agent based information retrieval system is presented. The paper
also discusses the framework of agent architecture for obtaining the best combination terms that serve as
an input query to the information retrieval system. The communication and cooperation among the agents
are also explained. Each agent has a task to perform in information retrieval.
Query expansion using novel use case scenario relationship for finding featur...IJECEIAES
Feature location is a technique for determining source code that implements specific features in software. It developed to help minimize effort on program comprehension. The main challenge of feature location research is how to bridge the gap between abstract keywords in use cases and detail in source code. The use case scenarios are software requirements artifacts that state the input, logic, rules, actor, and output of a function in the software. The sentence on use case scenario is sometimes described another sentence in other use case scenario. This study contributes to creating expansion queries in feature locations by finding the relationship between use case scenarios. The relationships include inner association, outer association and intratoken association. The research employs latent Dirichlet allocation (LDA) to create model topics on source code. Query expansion using inner, outer and intratoken was tested for finding feature locations on a Java-based open-source project. The best precision rate was 50%. The best recall was 100%, which was found in several use case scenarios implemented in a few files. The best average precision rate was 16.7%, which was found in inner association experiments. The best average recall rate was 68.3%, which was found in all compound association experiments.

Stacked Generalization of Random Forest and Decision Tree Techniques for Libr...IJEACS
The huge amount of library data stored in our modern research and statistic centers of organizations is springing up on daily bases. These databases grow exponentially in size with respect to time, it becomes exceptionally difficult to easily understand the behavior and interpret data with the relationships that exist between attributes. This exponential growth of data poses new organizational challenges like the conventional record management system infrastructure could no longer cope to give precise and detailed information about the behavior data over time. There is confusion and novel concern in selecting tools that can support and handle big data visualization that deals with multi-dimension. Viewing all related data at once in a database is a problem that has attracted the interest of data professionals with machine learning skills. This is a lingering issue in the data industry because the existing techniques cannot be used to remove or filter noise from relevant data and pad up missing values in order to get the required information. The aim is to develop a stacked generalization model that combines the functionality of random forest and decision tree to visualization library database visualization. In this paper, the random forest and decision tree techniques were employed to effectively visualize large amounts of school library data. The proposed system was implemented with a few lines of Python code to create visualizations that can help users at a glance understand and interpret the behavior of data and its relationships. The model was trained and tested to learn and extract hidden patterns of data with a cross-validation test. It combined the functionalities of both models to form a stacked generalization model that performed better than the individual techniques. The stacked model produced 95% followed by the RF which produced a 95% accuracy rate and 0.223600 RMSE error value in comparison with the DT which recorded an 80.00% success rate and 0.15990 RMSE value.
Semantic Search of E-Learning Documents Using Ontology Based Systemijcnes
The keyword searching mechanism is traditionally used for information retrieval from Web based systems. However, this system fails to meet the requirements in Web searching of the expert knowledge base based on the popular semantic systems. Semantic search of E-learning documents based on ontology is increasingly adopted in information retrieval systems. Ontology based system simplifies the task of finding correct information on the Web by building a search system based on the meaning of keyword instead of the keyword itself. The major function of the ontology based system is the development of specification of conceptualization which enhances the connection between the information present in the Web pages with that of the background knowledge.The semantic gap existing between the keyword found in documents and those in query can be matched suitably using Ontology based system. This paper provides a detailed account of the semantic search of E-learning documents using ontology based system by making comparison between various ontology systems. Based on this comparison, this survey attempts to identify the possible directions for future research.
