Keyword search is an intuitive paradigm for searching linked data sources on the web. We propose to route keywords only to relevant sources to reduce the high cost of processing keyword search queries over all sources.
This document discusses keyword query routing to identify relevant data sources for keyword searches over multiple structured and linked data sources. It proposes using a multilevel inter-relationship graph and scoring mechanism to compute relevance and generate routing plans that route keywords only to pertinent sources. This improves keyword search performance without compromising result quality. An algorithm is developed based on modeling the search space and developing a summary model to incorporate relevance at different levels and dimensions. Experiments showed the summary model preserves relevant information compactly.
The document proposes a novel method for routing keyword queries to only relevant data sources to reduce the high cost of processing queries over all sources. It employs a compact keyword-element relationship summary to represent relationships between keywords and data elements. A multilevel scoring mechanism is used to compute the relevance of routing plans based on scores at different levels. Experiments on 150 publicly available sources showed the method can compute valid, highly relevant plans in 1 second on average and routing improves keyword search performance without compromising result quality.

World Wide Web is large sized repository of
interlinked hypertext documents accessed via the Internet. Web
may contain text, images, video, and other multimedia data. The
user navigates through this using hyperlink. Search Engine gives
millions of results and applies Web mining techniques to order the
results. The sorted order of search results is obtained by applying
some special algorithms called—Page ranking algorithms. The
algorithm measures the importance of the pages by analyzing the
number of inlinked and outlinked pages. Our proposed system is
built on an idea that to rank the relevant pages higher in the
retrieved document set, an analysis of both page‘s text substance
and links information is required. The proposed approach is
based on the assumption that the effective weight of a term in a
page is computed by adding the weight of a term in the current
page and additional weight of the term in the linked pages. In
this chapter, we first study the nature of web pages, the various
link analysis ranking algorithms and their limitations and then
show the comparative analysis of the ranking scores obtained
through these approaches with our new suggested ranking
approach.
The growing number of datasets published on the Web as linked data brings both opportunities for high data
availability of data. As the data increases challenges for querying also increases. It is very difficult to search
linked data using structured languages. Hence, we use Keyword Query searching for linked data. In this paper,
we propose different approaches for keyword query routing through which the efficiency of keyword search can
be improved greatly. By routing the keywords to the relevant data sources the processing cost of keyword search
queries can be greatly reduced. In this paper, we contrast and compare four models – Keyword level, Element
level, Set level and query expansion using semantic and linguistic analysis. These models are used for keyword
query routing in keyword search.
Majority of the computer or mobile phone enthusiasts make use of the web for searching
activity. Web search engines are used for the searching; The results that the search engines get
are provided to it by a software module known as the Web Crawler. The size of this web is
increasing round-the-clock. The principal problem is to search this huge database for specific
information. To state whether a web page is relevant to a search topic is a dilemma. This paper
proposes a crawler called as “PDD crawler” which will follow both a link based as well as a
content based approach. This crawler follows a completely new crawling strategy to compute
the relevance of the page. It analyses the content of the page based on the information contained
in various tags within the HTML source code and then computes the total weight of the page. The page with the highest weight, thus has the maximum content and highest relevance.
This document discusses methods for measuring semantic similarity between words. It begins by discussing how traditional lexical similarity measurements do not consider semantics. It then discusses several existing approaches that measure semantic similarity using web search engines and text snippets. These approaches calculate word co-occurrence statistics from page counts and analyze lexical patterns extracted from snippets. Pattern clustering is used to group semantically similar patterns. The approaches are evaluated using datasets and metrics like precision and recall. Finally, the document proposes a new method that combines page count statistics, lexical pattern extraction and clustering, and support vector machines to measure semantic similarity.

A survey on Design and Implementation of Clever Crawler Based On DUST RemovalIJSRD
Now days, World Wide Web has become a popular medium to search information, business, trading and so on. A well know problem face by web crawler is the existence of large fraction of distinct URL that correspond to page with duplicate or nearby duplicate contents. In fact as estimated about 29% of web page are duplicates. Such URL commonly named as dust represent an important problem in search engines. To deal with this problem, the first efforts is focus on comparing document content to detect and remove duplicate document without fetching their contents .To accomplish this, the proposed methods learn normalization rules to transform all duplicate URLs into the same canonical form. A challenging aspect of this strategy is deriving a set of general and precise rules. The new approach to detect and eliminate redundant content is DUSTER .When crawling the web duster take advantage of a multi sequence alignment strategy to learn rewriting rules able to transform to other URL which likely to have same content . Alignment strategy that can lead to reduction of 54% larger in the number of duplicate URL.

Results showed this approach achieved around 60% precision, higher than other methods. Future work could include testing on larger datasets and code/queue optimizations.
Computing semantic similarity measure between words using web search enginecsandit
Semantic Similarity measures between words plays an important role in information retrieval,
natural language processing and in various tasks on the web. In this paper, we have proposed a
Modified Pattern Extraction Algorithm to compute the supervised semantic similarity measure
between the words by combining both page count method and web snippets method. Four
association measures are used to find semantic similarity between words in page count method
using web search engines. We use a Sequential Minimal Optimization (SMO) support vector
machines (SVM) to find the optimal combination of page counts-based similarity scores and
top-ranking patterns from the web snippets method. The SVM is trained to classify synonymous
word-pairs and non-synonymous word-pairs. The proposed Modified Pattern Extraction
Algorithm outperforms by 89.8 percent of correlation value.

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.

This document summarizes an approach to improve personalized ranking using associated edge weights. The key points are:
1) Personalized ranking aims to improve traditional search and retrieval by tailoring results to a user's interests. Authority flow approaches like PageRank and ObjectRank can be used for personalized ranking on entity-relationship graphs.
2) Edge-based personalization assigns different weights to edge types based on the user, affecting authority flow. The paper focuses on improving edge-based personalization by hybridizing the ScaleRank algorithm with k-means clustering.
3) ScaleRank approximates the DataApprox algorithm for ranking. The hybrid approach uses k-means clustering on ScaleRank output to further group related nodes,
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.
The document proposes an approach for enhancing information retrieval from invisible web data sources by integrating them. It presents algorithms for effectiveness calculation, estimation of queries and workload, centralized sample database and duplicate detection, and resource selection and integration. The proposed approach is evaluated experimentally and shown to achieve higher accuracy than existing algorithms based on an F-measure calculation on real datasets. Future work could involve building a more complete directory of invisible web resources and improving classification of sources into subject hierarchies.
This document discusses domain specific search and ranking model adaptation using a binary classifier. It proposes using a ranking adaptation support vector machine (RA-SVM) to adapt an existing broad-based ranking model to a new targeted domain with limited labeled data. The RA-SVM utilizes predictions from the existing model as well as domain specific features to build a robust ranking model for the target domain. It evaluates the adapted model using precision, recall, average precision and Kendall's Tau metrics. The goal is to minimize the amount of labeled data needed for the target domain while still achieving good performance.

Enhancing keyword search over relational databases using ontologiescsandit
Keyword Search Over Relational Databases (KSORDB) provides an easy way for casual users
to access relational databases using a set of keywords. Although much research has been done
and several prototypes have been developed recently, most of this research implements exact
(also called syntactic or keyword) match. So, if there is a vocabulary mismatch, the user cannot
get an answer although the database may contain relevant data. In this paper we propose a
system that overcomes this issue. Our system extends existing schema-free KSORDB systems
with semantic match features. So, if there were no or very few answers, our system exploits
domain ontology to progressively return related terms that can be used to retrieve more
relevant answers to user.

This document summarizes a research paper that proposes a system to enhance keyword search over relational databases using ontologies. The system builds structures during pre-processing like a reachability index to store connectivity information and an ontology concept graph. During querying, it maps keywords to concepts, uses the ontology to find related concepts and tuples, and generates top-k answer trees combining syntactic and semantic matches while limiting redundant results. The system is expected to perform better than existing approaches by reducing storage requirements through its approach to materializing neighborhood information in the reachability index.
IRJET-Multi -Stage Smart Deep Web Crawling Systems: A ReviewIRJET Journal
This document summarizes research on multi-stage smart deep web crawling systems. It discusses challenges in efficiently locating deep web interfaces due to their large numbers and dynamic nature. It proposes a three-stage crawling framework to address these challenges. The first stage performs site-based searching to prioritize relevant sites. The second stage explores sites to efficiently search for forms. An adaptive learning algorithm selects features and constructs link rankers to prioritize relevant links for fast searching.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Keyword query routing
1. 1.
KEYWORD QUERY ROUTING
ABSTRACT:
Keyword search is an intuitive paradigm for searching linked data sources on the
web. We propose to route keywords only to relevant sources to reduce the high cost of
processing keyword search queries over all sources. We propose a novel method for
computing top-k routing plans based on their potentials to contain results for a given keyword
query. We employ a keyword-element relationship summary that compactly represents
relationships between keywords and the data elements mentioning them. A multilevel scoring
mechanism is proposed for computing the relevance of routing plans based on scores at the
level of keywords, data elements, element sets, and subgraphs that connect these elements.
Experiments carried out using 150 publicly available sources on the web howed that valid
plan (precision@1 of 0.92) that are highly relevant (mean reciprocal rank of 0.89) can be
computed in 1 second on average on a single PC. Further, we show routing greatly helps to
improve the performance of keyword search, without compromising its result quality.
Algorithm:
Keyword Routing Plan:
Given the web graph W =(G,N,E) and a keyword query K, the mapping _ : K-
2G that associates a query with a set of data graphs is called a keyword routing plan
RP. A plan RP is considered valid w.r.t. K when the union set of its data graphs
contains a result for K.
The problem of keyword query routing is to find the top-k keyword routing
plans based on their relevance to a query. A relevant plan should correspond to the
information need as intended by the user.

EXISTING SYSTEM:
Existing work can be categorized into two main categories: There are schema-based
approaches implemented on top of off-the-shelf databases. A keyword query is processed by
mapping keywords to elements of the database (called keyword elements). Then, using the
schema, valid join sequences are derived, which are then employed to join (“connect”) the
computed keyword elements to form so-called candidate networks representing possible
results to the keyword query. Schema-agnostic approaches operate directly on the data.
Structured results are computed by exploring the underlying data graph. The goal is to find
structures in the data called Steiner trees (Steiner graphs in general), which connect keyword
elements.
PROPOSED SYSTEM:
We propose to route keywords only to relevant sources to reduce the high cost of
processing keyword search queries over all sources. We propose a novel method for
computing top-k routing plans based on their potentials to contain results for a given keyword
query. We employ a keyword-element relationship summary that compactly represents
relationships between keywords and the data elements mentioning them. A multilevel scoring
mechanism is proposed for computing the relevance of routing plans based on scores at the
level of keywords, data elements, element sets, and subgraphs that connect these elements.
Based on modeling the search space as a multilevel inter-relationship graph, we proposed a
summary model that groups keyword and element relationships at the level of sets, and
developed a multilevel ranking scheme to incorporate relevance at different dimensions.

4. 1.
We propose to investigate the problem of keyword query routing for keyword search
over large number of structured and Linked Data sources. Routing keywords only to
relevant sources can reduce the high cost of searching for structured results that span multiple
sources. To the best of our knowledge, the work presented in this paper represents the first
attempt to address this problem. A solution to keyword query routing can address these
problems by pruning unpromising sources and enabling users to select combinations that
more likely contain relevant results. For the routing problem, we do not need to compute
results capturing specific elements at the data level, but can focus on the more coarse-grained
level of sources.
3. Multilevel Inter-Relationship
The search space of keyword query routing using a multilevel inter-relationship
graph. The inter-relationships between elements at different levels are above Fig. A keyword
is mentioned in some entity descriptions at the element level. Entities at the element level are
associated with a set-level element via type. A set-level element is contained in a source.
There is an edge between two keywords if two elements at the element level mentioning
these keywords are connected via a path. We propose a ranking scheme that deals with
relevance at many levels.
4. Set Level
We extract keywords and relationships from the data. Then, based on the elements
and sets of elements in which they occur, we create keyword-element relationships.
Precomputing relationships (i.e., paths) between data elements are typically performed for
keyword search to improve online performance. These relationships are stored in specialized
indexes and retrieved at the time of keyword query processing to accelerate the search for
Steiner graphs. For database selection, relationships between keywords are also precomputed.
This work neither considers relationships between keywords nor relationships between data
elements but between keyword-elements that collectively represent the keywords and the data
elements in which they occur.
