Query formulation in web search [PDF]

open access: yesProceedings of the American Society for Information Science and Technology, 2009
AbstractOver 2 billion searches are conducted daily on Web search engines. Some Web searches are re‐finding what was seen before, but many searches are query reformulation or refinements as attempts to retrieve better results. Previous studies have examined query formulation and reformulation from the mid‐seventies to today, including online ...

Semantic Web Search Based on Ontological Conjunctive Queries [PDF]

open access: yesJournal of Web Semantics, 2010
Many experts predict that the next huge step forward in Web information technology will be achieved by adding semantics to Web data, and will possibly consist of (some form of) the Semantic Web. In this paper, we present a novel approach to Semantic Web search, called Serene, which allows for a semantic processing of Web search queries, and for ...

Semantic tagging of web search queries [PDF]

open access: yesProceedings of the Joint Conference of the 47th Annual Meeting of the ACL and the 4th International Joint Conference on Natural Language Processing of the AFNLP: Volume 2 - ACL-IJCNLP '09, 2009
We present a novel approach to parse web search queries for the purpose of automatic tagging of the queries. We will define a set of probabilistic context-free rules, which generates bags (i.e. multi-sets) of words. Using this new type of rule in combination with the traditional probabilistic phrase structure rules, we define a hybrid grammar, which ...

Organizing query completions for web search [PDF]

open access: yesProceedings of the 19th ACM international conference on Information and knowledge management, 2010
All state-of-the-art web search engines implement an auto-completion mechanism - an assistive technology enabling users to effectively formulate their search queries by predicting the next characters or words that they are likely to type. Query completions (or suggestions) are typically mined from past user interactions with the search engine, e.g ...
