Contextual pdf search6/22/2023 ![]() ![]() Major search services such as Google, Bing, and Yahoo also have a system of automatically inferring the context of particular user queries. Watson's ability to build off previous knowledge allows queries to be automatically filtered for similar contexts in order to supply precise results. As related terms and relevant documents are matched against the query, Watson's hypothesis is modified to reflect the new information provided through unstructured data based on information it has obtained in previous situations. When presented with a query Watson creates a hypothesis that is evaluated against its present bank of knowledge based on previous questions. IBM's Watson Project aims to create a cognitive technology that dynamically learns as it processes user queries. There are other systems being developed that are working on automatically inferring the context of user queries based on the content of other documents they view or edit. Bing allows users to search within a time range, by file type, by location, language, and more. Bing also uses a similar set of search operators to assist users in explicitly narrowing down the context of their queries. Google has an extensive list of search operators that allow users to explicitly limit results to fit their needs such as restricting certain file types or removing certain words. Google allows users to filter by type: Images, Maps, Shopping, News, Videos, Books, Flights, and Apps. Aspects of supplied context do appear on major search engines with better user-interaction such as Google and Bing. Learning the interface of programs like Inquirus can prove challenging for general users without knowledge of search metrics. Įxplicitly supplied context effectively increases the precision of results, however, these search services tend to suffer from poor user-experience. If another user is searching for general information on the topic rather than research papers, they can specify the GenScore attribute to have a heavier weight. For example, a user looking for research papers can specify documents with “references” or “abstracts” to be rated higher. When searching on Inquirus 2, users enter a query and specify constraints such as the information need category, maximum number of hits, and display formats. Inquirus 2 is a Meta search engine that acts as a mediator between the user query and other search engines. The next step in contextualizing search is for the search service itself to request information that narrows down the results, such as Google asking for a time range to search within.Ĭertain search services, including many Meta search engines, request individual contextual information from users to increase the precision of returned documents. For example, users looking for the menu portion of a website can add “menu” to the end of their query to provide the search engine with context of what they need. ![]() ![]() ![]() Users have limited control over the context of their query based on the words they use to search with. HTML pages that have a higher occurrence of query keywords within their content are not rated higher. Web search engines scan HTML pages for content and return an index rating based on how relevant the content is to the entered query. The basic form of contextual search is the process of scanning the full-text of a query in order to understand what the user needs. Rather, contextual search attempts to increase the precision of results based on how valuable they are to individual users. Contextual search services differ from current search engines based on traditional information retrieval that return lists of documents based on their relevance to the query. ( May 2015)Ĭontextual search is a form of optimizing web-based search results based on context provided by the user and the computer being used to enter the query.
