Annotation for query result records based on domain specific ontologyijnlc
The World Wide Web is enriched with a large collection of data, scattered in deep web databases and web
pages in unstructured or semi structured formats. Recently evolving customer friendly web applications
need special data extraction mechanisms to draw out the required data from these deep web, according to
the end user query and populate to the output page dynamically at the fastest rate. In existing research
areas web data extraction methods are based on the supervised learning (wrapper induction) methods. In
the past few years researchers depicted on the automatic web data extraction methods based on similarity
measures. Among automatic data extraction methods our existing Combining Tag and Value similarity
method, lags to identify an attribute in the query result table. A novel approach for data extracting and
label assignment called Annotation for Query Result Records based on domain specific ontology. First, an
ontology domain is to be constructed using information from query interface and query result pages
obtained from the web. Next, using this domain ontology, a meaning label is assigned automatically to each
column of the extracted query result records.

Annotating Search Results from Web DatabasesSWAMI06
An increasing number of databases have become web accessible through HTML form-based search interfaces. The data
units returned from the underlying database are usually encoded into the result pages dynamically for human browsing. For the
encoded data units to be machine processable, which is essential for many applications such as deep web data collection and Internet
comparison shopping, they need to be extracted out and assigned meaningful labels. In this paper, we present an automatic
annotation approach that first aligns the data units on a result page into different groups such that the data in the same group have the
same semantic. Then, for each group we annotate it from different aspects and aggregate the different annotations to predict a final
annotation label for it. An annotation wrapper for the search site is automatically constructed and can be used to annotate new result
pages from the same web database. Our experiments indicate that the proposed approach is highly effective.

Comparative analysis of relative and exact search for web information retrievaleSAT Journals
Abstract The volume of data on web repository is huge. To get specific and precise information for the web repository is a big challenge. Existing Information Retrieval (IR) techniques, given by contemporary researchers, are very useful in field of IR. Here, the authors have implemented and tested two of the techniques from the fields of IR. The authors dealt with Relative Search and Exact Search techniques one by one. Initially relative search tested on web repository data using web mining tool and then its results are analyzed. In the same manner, the exact search technique of IR tested on web repository data and the results are measured. The researchers have experienced the significant importance on exact search and relative search. The focused of the research paper is to retrieve relevant information from the web information repository. With the use of two searching criteria these can be done. With the use of the suggested methods the searchers may retrieve a relevant web data in a fewer time. Key Words: Web data Mining, Exact Search, Relative Search, PR, TM, CD, VSM and TASE
Comparable Analysis of Web Mining Categoriestheijes
Web Data Mining is the current field of analysis which is a combination of two research area known as Data Mining and World Wide Web. Web Data Mining research associates with various research diversities like Database, Artificial Intelligence and Information redeem. The mining techniques are categorized into various categories namely Web Content Mining, Web Structure Mining and Web Usage Mining. In this work, analysis of mining techniques are done. From the analysis it has been concluded that Web Content Mining has unstructured or semi- structure view of data whereas Web Structure Mining have linked structure and Web Usage Mining mainly includes interaction.
While the world is witnessing an information revolution unprecedented and great speed in the growth of databases in all aspects. Databases interconnect with their content and schema but use different elements and structures to express the same concepts and relations, which may cause semantic and structural conflicts. This paper proposes a new technique for integration the heterogeneous eXtensible Markup Language (XML) schemas, under the name XDEHD. The returned mediated schema contains all concepts and relations of the sources without duplication. Detailed technique divides into three steps; First, extract all subschemas from the sources by decompose the schemas sources, each subschema contains three levels, these levels are ancestor, root and leaf. Thereafter, second, the technique matches and compares the subschemas and return the related candidate subschemas, semantic closeness function is implemented to measures the degree how similar the concepts of subschemas are modelled in the sources. Finally, create the medicate schema by integration the candidate subschemas, and then obtain the minimal and complete unified schema, association strength function is developed to compute closely of pair in candidate subschema across all data sources, and elements repetition function is employed to calculate how many times each element repeated between the candidate subschema.
Comparison of Semantic and Syntactic Information Retrieval System on the basi...Waqas Tariq
In this paper information retrieval system for local databases are discussed. The approach is to search the web both semantically and syntactically. The proposal handles the search queries related to the user who is interested in the focused results regarding a product with some specific characteristics. The objective of the work will be to find and retrieve the accurate information from the available information warehouse which contains related data having common keywords. This information retrieval system can eventually be used for accessing the internet also. Accuracy in information retrieval that is achieving both high precision and recall is difficult. So both semantic and syntactic search engine are compared for information retrieval using two parameters i.e. precision and recall.
Information residing in relational databases and delimited file systems are inadequate for reuse and sharing over the web. These file systems do not adhere to commonly set principles for maintaining data harmony. Due to these reasons, the resources have been suffering from lack of uniformity, heterogeneity as well as redundancy throughout the web. Ontologies have been widely used for solving such type of problems, as they help in extracting knowledge out of any information system. In this article, we focus on extracting concepts and their relations from a set of CSV files. These files are served as individual concepts and grouped into a particular domain, called the domain ontology. Furthermore, this domain ontology is used for capturing CSV data and represented in RDF format retaining links among files or concepts. Datatype and object properties are automatically detected from header fields. This reduces the task of user involvement in generating mapping files. The detail analysis has been performed on Baseball tabular data and the result shows a rich set of semantic information.
Using Page Size for Controlling Duplicate Query Results in Semantic WebIJwest
Semantic web is a web of future. The Resource Description Framework (RDF) is a language
to represent resources in the World Wide Web. When these resources are queried the problem of duplicate
query results occurs. The present techniques used hash index comparison to remove duplicate query
results. The major drawback of using the hash index to remove duplicate query results is that, if there is a
slight change in formatting or word order, then hash index is changed and query results are no more
considered as duplicate even though they have same contents. We presented an algorithm for detection and
elimination of duplicate query results from semantic web using hash index and page size comparisons.
Experimental results showed that the proposed technique removed duplicate query results from semantic
web efficiently, solved the problems of using hash index for duplicate handling and could be embedded in
existing SQL-Based query system for semantic web. Research could be carried out for certain flexibilities
in existing SQL-Based query system of semantic web to accommodate other duplicate detection techniques
as well.
Improve information retrieval and e learning usingIJwest
The Web-based education and E-Learning has become a very important branch of new educational technology. E-learning and Web-based courses offer advantages for learners by making access to resources and learning objects very fast, just-in-time and relevance, at any time or place. Web based Learning Management Systems should focus on how to satisfy the e-learners needs and it may advise a learner with most suitable resources and learning objects. But Because of many limitations using web 2.0 for creating E-learning management system, now-a-days we use Web 3.0 which is known as Semantic web. It is a platform to represent E-learning management system that recovers the limitations of Web 2.0.In this paper we present “improve information retrieval and e-learning using mobile agent based on semantic web technology”. This paper focuses on design and implementation of knowledge-based industrial reusable, interactive, web-based training activities at the sea ports and logistics sector and use e-learning system and semantic web to deliver the learning objects to learners in an interactive, adaptive and flexible manner. We use semantic web and mobile agent to improve Library and courses Search. The architecture presented in this paper is considered an adaptation model that converts from syntactic search to semantic search. We apply the training at Damietta port in Egypt as a real-world case study. we present one of possible applications of mobile agent technology based on semantic web to management of Web Services, this model improve the information retrieval and E-learning system.
Ontology languages are used in modelling the semantics of concepts within a particular domain and the relationships between those concepts. The Semantic Web standard provides a number of modelling languages that differ in their level of expressivity and are organized in a Semantic Web Stack in such a way that each language level builds on the expressivity of the other. There are several problems when one attempts to use independently developed ontologies. When existing ontologies are adapted for new purposes it requires that certain operations are performed on them. These operations are currently performed in a semi-automated manner. This paper seeks to model categorically the syntax and semantics of RDF ontology as a step towards the formalization of ontological operations using category theory.
Selection of Relevant Fields of Searchable Form Based on Meta Keywords Freque...AM Publications
Crawling the hidden web is a very challenging problem due to the number of active web pages on the web is
increasing exponentially. Hidden web contents are highly relevant to every information need for searching purpose. Hidden
web contents are usually behind the searchable form, ignore by all traditional crawler so hidden web crawler used for this
purpose. Because of hidden web contains a vast amount of data so it is necessary to crawl only specific hidden data. In this
paper, a meta keywords frequencies based architecture has been proposed to carry this work.
AUTOMATIC CONVERSION OF RELATIONAL DATABASES INTO ONTOLOGIES: A COMPARATIVE A...IJwest
Constructing ontologies from relational databases is an active research topic in the Semantic Web domain.
While conceptual mapping rules/principles of relational databases and ontology structures are being
proposed, several software modules or plug-ins are being developed to enable the automatic conversion of
relational databases into ontologies. However, the correlation between the resulting ontologies built
automatically with plug-ins from relational databases and the database-toontology mapping principles has
been given little attention. This study reviews and applies two Protégé plug-ins, namely, DataMaster and
OntoBase to automatically construct ontologies from a relational database. The resulting ontologies are
further analysed to match their structures against the database-to-ontology mapping principles. A
comparative analysis of the matching results reveals that OntoBase outperforms DataMaster in applying
the database-to-ontology mapping principles for automatically converting relational databases into
ontologies
The Web is a universal medium for information, data and knowledge exchange. The Semantic Web is an extension of the World Wide Web, ``in which information is given well-defined meaning, better enabling computers and people to work in cooperation''\cite{semweb:lee}. RDF, together with SparQL, provide a powerful mechanism for describing and interchanging metadata on the web. This paper presents briefly the two concepts - RDF, SparQL - and three of the most popular frameworks (written in Java) that offer support for RDF: Jena, Sesame and JRDF.

The previous research has focused on quick and efficient generation of wrappers; the
development of tools for wrapper maintenance has received less attention. This is an important research
problem because Web sources often change in ways that prevent the wrappers from extracting data
correctly. Present an efficient algorithm that extract unstructured data to structural data from web. The
wrapper verification system detects when a wrapper is not extracting correct data, usually because the
Web source has changed its format. The Verification framework automatically recovers data using
Dimension Reduction Techniques from changes in the Web source by identifying data on Web pages.
After apply wrapped data to One Class Classification in Numerical features for avoid classification
problem. Finally, the result data apply in Top-K query for provide best rank based on probabilities
scores. Wrapper verification system relies on one-class classification techniques to beat previous
weaknesses to identify the problem by analysing both the signature and the classifier output. If there are
sufficient mislabelled slots, a technique to find a pattern could be explored.

A language independent web data extraction using vision based page segmentati...eSAT Journals
Abstract Web usage mining is a process of extracting useful information from server logs i.e. user’s history. Web usage mining is a process of finding out what users are looking for on the internet. Some users might be looking at only textual data, where as some others might be interested in multimedia data. One would retrieve the data by copying it and pasting it to the relevant document. But this is tedious and time consuming as well as difficult when the data to be retrieved is plenty. Extracting structured data from a web page is challenging problem due to complicated structured pages. Earlier they were used web page programming language dependent; the main problem is to analyze the html source code. In earlier they were considered the scripts such as java scripts and cascade styles in the html files. When it makes different for existing solutions to infer the regularity of the structure of the WebPages only by analyzing the tag structures. To overcome this problem we are using a new algorithm called VIPS algorithm i.e. independent language. This approach primary utilizes the visual features on the webpage to implement web data extraction. Keywords: Index terms-Web mining, Web data extraction.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

----------------------------------------------------------------ABSTRACT---------------------------------------------------
Information Extraction (IE) on the web is the task of automatically extracting knowledge from text. Web
Information Extraction (WIE) systems have recently been able to extract massive quantities of relational data
from online text. This massive body of text which are now available on the World Wide Web do presents an
unparalleled opportunity for information extraction. However, this information extraction on the Web is
challenging due to the vast variety of distinct concepts and structured expressed. The explosive growth and
popularity of the worldwide web has resulted in a huge amount of information sources on the Internet.
However, due to the heterogeneity, diversity and the lack of structure of Web information sources, access to this
huge collection of information has been limited to browsing and searching.
Information extraction is done from unstructured and ungrammatical text on the Web. They can be classified
Ads, Auction listings, and web postings forums. As the data is unstructured and ungrammatical, this information
extraction precludes the use of rule-based methods that rely on consistent structures within the text. It can be
natural language processing techniques that rely on grammar. Posts are full of useful information, as defined by
the attributes that compose the entity within the post.
Currently accessing the data within posts does not go much beyond the search of keywords. This is in particular
because the unstructured and ungrammatical nature of posts makes the extraction difficult, so many a times the
attributes remain hidden or embedded within the posts. Also these data sources are ungrammatical, since they
do not conform to the exact rules of written language. Therefore, Natural Language Processing (NLP) based
information extraction techniques are inappropriate. The ability to process and understand this information
becomes more crucial, as more and more information comes online.
Also Data integration attacks this problem by letting users query heterogeneous data sources within a unified
query framework; it can be combining the results to make understanding easily. However, while data
integration can integrate data from structured sources such as databases, Web Services and even semi-
structured sources such as that extracted data from Web pages, this leaves out the large class of useful
information- Unstructured and Ungrammatical data sources.
Thus we proposed a system based Machine Learning technique to obtain the data records which are structured,
from different unstructured and non-template based websites. Thus the proposed approach will be implemented
by collection of known entities and their attributes, which are been referred as “reference set," A reference set
can be constructed from structured sources, such as databases, or scraped from semi-structured sources such as
collections of web pages. Also it can be constructed automatically from the unstructured, ungrammatical text
itself. Thus this project implements methods to exploit the reference sets for extraction using the machine
learning techniques. The machine learning approach provides exact and higher accuracy extractions and also
deals with ambiguous extractions, although at the cost of requiring human effort to label training data.

I. INTRODUCTION
The Internet provides access to numerous sources of useful information which are in the form of text.
In recent times, there has been much interest in building systems that gather such information on a user's behalf.
But because people format such information resources for use, mechanically extracting their content is not easy.
2. Scaling the Information Extraction...
www.theijes.com The IJES Page 37
Systems using such resources typically use hand-coded wrappers, i.e. customized procedures for information
extraction. Information extraction from unstructured, ungrammatical text on the Web such as classified ads,
auction listings, and forum postings is a tough work. This information extraction precludes the use of rule-based
methods that rely on consistent structures within the text or natural language processing techniques that rely on
grammar, Since the data is unstructured and ungrammatical,Posts data consists of useful information, as defined
by the attributes that compose the entity within the post. For example, consider certain posts about cars from the
online classified service. Each used car for sale is composed of attributes that define this car; and if we could
access the individual attributes then we could include such sources in data integration systems, and answer the
interesting queries. Such a query might require combining the structured database of safety ratings with the
posts of the classified ads and the car review websites.
However, currently accessing the data within posts does not go much beyond search of keywords. This
is specifically because the ungrammatical, unstructured nature of posts makes extraction difficult, so the
attributes remain entrenched within the posts. These data sources are ungrammatical, since they do not conform
to the proper rules of written language. Therefore, Natural Language Processing (NLP) based information
extraction techniques are not suitable. Also the posts are unstructured since the structure can differ vastly
between each listing. So, wrapper based extraction techniques will also not work either. Even if one can extract
the data from within posts, you would need to assure that the extracted values map to the same value for
accurate querying.
II. LITERATURE SURVEY
Existing Systems
The combination of various input documents and also variation of extraction can cause different
degrees of task difficulties. Since various Information Extraction systems are designed for various IE tasks, it is
not fair to compare them directly. However, analyzing what task an IE system targets and how it performs the
task, can be used to evaluate this system and possibly extend to other task domains.
TSIMMIS is one of the first approaches that gives a skeleton for manual building of Web wrappers [7]. The
main component of this project is a wrapper that takes as input a specification file that declaratively states
where the data of interest is located on the pages and how the data should be “packaged” into objects states
(by a sequence of commands given by programmers). Each of this command is having the form of:
[variables, source, pattern], where source specifies the input text to be considered, pattern specifies how to
find the text of interest within the source, and variables are a list of variables that hold the extracted results.
The special symbol „*‟ in a pattern means discard, and „#‟ means save in the variables.
WebOQL is a functional language that can be used as a query language on the Web, for semi structured
data and restructuring website as well[6]. The main data structure provided by WebOQL is the hypertree.
Hypertrees are arc-labeled ordered trees which can be used to model a relational table, a Bibtex file, a
directory hierarchy, etc. The abstraction level of the data model is suitable to support collections, nesting,
and ordering.
W4F (Wysiwyg Web Wrapper Factory) is a Java toolkit to generate Web wrappers [8]. The wrapper
development process consists of three independent layers:- retrieval, extraction and mapping layers. In the
retrieval layer, a to-be processed document is retrieved (from the Web through HTTP protocol), cleaned
and then fed to an HTML parser that constructs a parse tree following the Document Object Model (DOM).
In the extraction layer, extraction rules are applied on the parse tree to extract information and then store
them into the W4F internal format called Nested String List (NSL).
This project objective is to exploit those reference sets for extraction using both automatic techniques and
machine learning techniques. The automatic technique provides a scalable and accurate approach to extraction
from unstructured, ungrammatical text.
The machine learning approach provides even higher accuracy extractions and deals with ambiguous
extractions, although at the cost of requiring human effort to label training data. The results demonstrate that
reference-set based extraction outperforms the current state-of-the-art systems that rely on structural or
grammatical clues, which is actually not appropriate for unstructured, ungrammatical text. Even the fully
automatic case, which constructs its own reference set for automatic extraction, is competitive with the current
state-of-the-art techniques that require labeled data. Reference-set based extraction from unstructured,
ungrammatical text allows for a whole category of sources to be queried, allowing for their inclusion in data
integration systems that were previously limited to structured and semi-structured sources.

III. PROBLEM DEFINATION
The ability to process and understand this information which comes online becomes more and more
crucial. While data integration can integrate data from structured sources such as databases, semi-structured
sources such as that extracted from Web pages, and even Web Services, which ultimately leaves out a large
class of useful information - Unstructured and Ungrammatical data sources. The task is to identify such
unstructured, ungrammatical data as “posts". Posts are ranging in source from classified ads, forum postings,
and auction listings to blog titles or paper references. The aim of the project is to structure the sources of posts,
such that they can be queried and included in data integration systems.

1. Learning System
A learning system is responsible for learning a new set of extraction rules for specific sites. A single
web site may contain pages conforming to multiple different templates, from each website all samples of pages
are collected and are clustered using Shingle based signature which is computed for each web page based on
html tags.
2. Data Extraction System
An Extraction system, the learnt rules are applied to the stream of crawled wed pages to extract records
from them. For each incoming web page, the shingle based signature and page URL are used to find the
matching rule for the page, which is then applied to extract the record for the page.
3. User Search Query System
A Search Query System, are used to search matching records based user query. For each request query
will be matched based on the rules of learning system.
The key contribution of the project is for information extraction that exploits reference sets, rather than grammar
or structure based techniques. The project includes the following contributions:
An automatic learning system for matching and extraction of reference set.
A method that selects the appropriate reference sets from a repository and uses them for extraction and
annotation without training data.
An automatic method for constructing reference sets from the posts themselves..
An automatic method for web post record extraction using reference set for searching accurate
information.
The proposed approach will be implemented by collection of known entities and their attributes, which refer as
“reference set," A reference set can be constructed from structured sources, such as databases, or scraped from
semi-structured sources such as collections of Web pages. A reference set can even be constructed automatically
from the unstructured, ungrammatical text itself. It follows the following methodology for information
extraction from unstructured, ungrammatical data sources:
1. Automatically Choosing the Reference Sets
2. Matching Posts to the Reference Set
3. Extraction using reference sets
4. Automatically Constructing Reference Sets for Extraction
5. A Learning Approach to Reference-Set Based Extraction
6. Extracting Data from unstructured data sources.
V. RESEARCH ELABORATIONS
5.1 Implementation Methodology
Web browsers contain implementations of World Wide Web Consortium-recommended specifications,
and software development tools contain implementations of programming languages.
5.1.1. Grouping similar pages:
A large set of similar structure web pages will be grouped from the website. Although Web pages within a
cluster, to a large extent, have similar structure, they also exhibit minor structural variations because of optional,
disjunctive, extraneous, or styling sections. To ensure high recall at low cost, we need to ensure that the page
sample set that is annotated has a small number of pages and captures most of the structural variations in the
cluster. One way to create a relational data set from the posts is to define a schema and then fill in values for the
schema elements using techniques such as information extraction. This is sometimes called semantic annotation.
5.1.2. Extracting Reference Sets:
Extracting Reference Sets implements the approach to creating relational data sets from unstructured and
ungrammatical posts exploits reference sets. A reference set consists of collections of known entities with the
associated, common attributes. A reference set can be an online (or offline) set of reference documents.First we
label each token with a possible attribute label or as “junk" to be ignored. After all the tokens in a post are
labeled, then clean each of the extracted labels.
5. Scaling the Information Extraction...
www.theijes.com The IJES Page 40
To begin the extraction process, the post is broken into tokens. Using the first post from Table 1 as an example,
set of tokens becomes, {“93", “civic", “5speed",...}. Each of these tokens is then scored against each attribute of
the record from the reference set that was deemed the match.
To score the tokens, the extraction process builds a vector of scores, VIE. VIE is composed of vectors which
represent the similarities between the token and the attributes of the reference set.
Fig 5.1: Extraction process for attributes
VIE=<common scores (“civic"),
IE scores (“civic", “Honda"),
IE scores (“civic", “Civic"),
IE scores (“civic", “1993")>
More generally, for a given token, VIE looks like:
VIE=<common scores (token),
IE scores (token, attribute1),
IE scores (token, attribute2)
. . . ,
IE scores (token, attributen)>
Each VIE is then passed to a structured SVM, trained to give it an attribute type label, such as make, model, or
price. Since there are many irrelevant tokens in the post that should not be annotated, the SVM learns that any
VIE that does associate with a learned attribute type should be labeled as “junk", which can then be ignored.
Without the benefits of a reference set, recognizing junk is difficult because the characteristics of the text in the
posts are unreliable.To use a reference set to build a relational data set, exploit the attributes in the reference set
to determine the attributes from the post that can be extracted. The first step is to find the best matching member
of the reference set for the post. This is called the “record linkage" step. By matching a post to a member of the
reference set we can define schema elements for the post using the schema of the reference set, and we can
provide standard attributes for these attributes by using the attributes from the reference set when a user queries
the posts.
Fig 5.2- Creating relational data from unstructured sources
6. Scaling the Information Extraction...
www.theijes.com The IJES Page 41
Next, perform information extraction to extract the actual values in the post that match the schema elements
defined by the reference set. This step is the information extraction step. During the information extraction step,
the parts of the post are extracted that best match the attribute values from the reference set member chosen.
First determine the set of matching rules for the page based on the page URL. The final rule is subsequently
chosen based on the page shingle vector.
Fig 5.3- Matching a post to the reference set
5.1.3. Extracting Web Page Records:
Extracting Web Page Records implementation based on the learnt rules are applied to the stream of crawled
wed pages to extract records from them. For each incoming web page, the shingle based signature and page
URL are used to find the matching rule for the page, which is then applied to extract the record for the page. The
extracted record will be stored in the database for user query search.
5.1.4. User Search Query:
User Search Query System implementation for user to search matching records based user query input. For
each request query will be matched based on the rules of learning system. User input may not be in appropriate
syntax or semantics, the system do an auto correction of the input using learning system data set and pose an
appropriate query for search.
VI. RESULTS AND DISCUSSION
We will evaluate the accuracy of query and performance of the system we implemented the various data files
gathered for 3 different websites. The input file will be html files.
To measure accuracy of query and performance, we compared, in terms of query error rates and accuracy results
obtained by running our implemented system on the gathered data from various sites. The system first extract
the reference sets required for query correction using Learning System mechanism, and then runs the web data
records process to build web link and URL database for user query matching. In last we runs user query system
where user pose a query input for searching required contents.

VII. CONCLUSION
Keyword search over semi-structured and structured data offers users great opportunities to explore
better-organized data. Our approach, reference-set based extraction exploits a reference set. By using reference
sets for extraction, instead of grammar or structure, our technique free the assumption that posts require
structure or grammar. This project investigates information extraction from unstructured, ungrammatical text on
the Web such as web postings. Since the data is unstructured and ungrammatical, this information extraction
precludes the use of rule-based methods that rely on consistent structures within the text or natural language
processing techniques that rely on grammar. Our work describes extraction using a reference set, which define
as a collection of known entities and their attributes. The project implements an automatic technique to provide
10. Scaling the Information Extraction...

a scalable and accurate approach to extraction from unstructured, ungrammatical text. The machine learning
approach provides even higher accuracy extractions and deals with ambiguous extractions, although at the cost
of requiring human effort to label training data. The results demonstrate that reference-set based extraction
outperforms the current state-of-the-art systems that rely on structural or grammatical clues, which is not
appropriate for unstructured, ungrammatical text. Reference-set based extraction from unstructured,
ungrammatical text allows for a whole category of sources to be queried, allowing for their inclusion in data
integration systems that were previously limited to structured and semi-structured sources.
Textual characteristics of the posts make it difficult to automatically construct the reference set. One future topic
of research is a more robust and accurate method for automatically constructing reference sets from data when
the data does not fit the criteria for automatic creation. This is a larger new topic that may involve combining the
automatic construction technique in this thesis with techniques that leverage the entire web for extracting
attributes for entities. Along these lines, in certain cases it may simply not be possible for an automatic method
to discover a reference set.
