Compressed data structures for annotated web search

Soumen Chakrabarti, Sasidhar Kasturi, Bharath Balakrishnan, Ganesh Ramakrishnan, Rohit Saraf
2012 Proceedings of the 21st international conference on World Wide Web - WWW '12  
Entity relationship search at Web scale depends on adding dozens of entity annotations to each of billions of crawled pages and indexing the annotations at rates comparable to regular text indexing.  ...  These data structures cannot be readily built upon standard inverted indices. Here we present a Web scale entity annotator and annotation index.  ...  Thanks to Natassa Ailamaki for vertical database references and Sebastiano Vigna for much help with MG4J.  ...

Entity Synonyms for Structured Web Search

Tao Cheng, Hady W. Lauw, Stelios Paparizos
2012 IEEE Transactions on Knowledge and Data Engineering  
Therefore, recognizing the alternative ways people use to reference an entity, is crucial for structured web search.  ...  In such scenarios, there is often a mismatch between the values of structured data (how content creators describe entities) and the web queries (how different users try to retrieve them).  ...  Index Terms-Entity synonym, fuzzy matching, structured data, web query, query log.  ...

Heterogeneous web data search using relevance-based on the fly data integration

Daniel M. Herzig, Thanh Tran
2012 Proceedings of the 21st international conference on World Wide Web - WWW '12  
For a structured query adhering to the vocabulary of just one source, the so-called seed query, we construct an entity relevance model (ERM), which captures the content and the structure of the seed query  ...  Searching over heterogeneous structured data on the Web is challenging due to vocabulary and structure mismatches among different data sources.  ...  Also, we thank Julien Gaugaz and the L3S Research Center for providing us their versions of the IMdb and Amazon datasets.  ...

Semantic and distributed entity search in the web of data

2012 SIGIR Forum  
The main contributions are as follows: • We develop a hybrid approach to search in the Web of Data, using elements from traditional information retrieval and structured retrieval alike. • We formalise  ...  The Web of Data (WoD) is an extension of the current web, where not only documents are interlinked by means of hyperlinks but also data in terms of predicates.  ...  However, current state-of-the-art web search engines crawl the We also performed an experiment with a large network of N P =1,000 peers to study the scalability of hybrid aggregation.  ...

Searching Web 2.0 Data Through Entity-Based Aggregation [chapter]

Ekaterini Ioannou, Yannis Velegrakis
2016 Lecture Notes in Computer Science  
Entity searching over Web 2.0 data facilitates the retrieval of relevant information from the plethora of data available in semantic and social web applications.  ...  Entity-based searching has been introduced as a way of allowing users and applications to retrieve information about a specific real world object such as a person, an event, or a location.  ...  The entity store provides a repository of entities along with an index for efficient entity retrieval.  ...

Event Search and Analytics

Dhruv Gupta
2016 Proceedings of the Ninth ACM International Conference on Web Search and Data Mining - WSDM '16  
Semantic annotations such as named entities, geographic locations, and temporal expressions can help us mine events from the given corpora.  ...  I pose three problems that can help unlock this knowledge vault in semantically annotated text corpora: i. identifying important events; ii. semantic search; and iii. event analytics.  ...  The IR system is designed to incorporate the time dimension in an index; thus retrieving documents with text and time similarity.  ...

Semantically driven snippet selection for supporting focused web searches

Iraklis Varlamis, Sofia Stamou
2009 Data & Knowledge Engineering  
During search, the users visit a web search engine and use an interface to specify a query (typically comprising a few keywords) that best describes their information need.  ...  In general, text snippets, extracted from the retrieved pages, are an indicator of the pages' usefulness to the query intention and they help the users browse search results and decide on the pages to  ...  We applied our snippet selection technique (SemSS) to a number of searches that we have performed using real web data and we compared its performance to the performance of existing passage retrieval algorithms  ...

Exploiting web search engines to search structured databases

Sanjay Agrawal, Kaushik Chakrabarti, Surajit Chaudhuri, Venkatesh Ganti, Arnd Christian Konig, Dong Xin
2009 Proceedings of the 18th international conference on World wide web - WWW '09  
We establish and exploit the relationships between web search results and the items in structured databases to identify the relevant structured data items for a much wider range of queries.  ...  The relevant structured data items are then returned to the user along with web search results. However, each structured database is searched in isolation.  ...  Entity Retrieval: The task of entity retrieval is to lookup the DocIndex for a given document identifier and retrieve the entities extracted from the document (at document indexing time) along with their  ...
