This patent publication describes a system for generating search results based on a user's natural language query. The system considers information previously accessed by the user across various devices and applications, such as email and web history.

This patent explores open information extraction, a new extraction paradigm has been developed in which a system makes a single data-driven pass over a corpus of text, extracting a large set of relational tuples without requiring any human input

The Identifying Subjective Attributes by Curation Signal Analysis patent outlines a system and method for automatically identifying and predicting subjective qualities of entities like media or articles.

This patent specification details a system for enhancing search queries by using concepts, which are groups of words with a unified meaning, as contextual clues for suggesting better search terms. The system identifies these concepts within a user's query and then analyses historical search data to find common substitutions for other terms appearing alongside these concepts. By understanding the context provided by a concept like "New York Times", the search engine can more accurately suggest replacing "Puzzle" with "Crossword" compared to a general substitution. This approach allows for more nuanced and relevant query revisions by considering multi-word contexts without excessive computational load, ultimately aiming to improve search result quality.

This patent application details a method for ranking nodes within a linked database, such as the World Wide Web. The described PageRank algorithm assigns importance scores to documents based on the quantity and quality of links pointing to them, essentially a recursive system where a link from a highly-ranked page carries more weight.

Today we will explore the Document Scoring Based on Document Inception Date patent, a system that calculates a document score partly based on its age and the rate at which links to it are created.

The patent Clustering of Search Results escribes a system and method for clustering search results to improve their quality.

The Multi Source Extraction and Scoring of Short Query Answers patent dentifies a candidate passage within the search results and evaluates its accuracy using context passages from other sources. An accuracy score prediction engine is used to determine whether the candidate passage is likely to provide an accurate answer.

This week we explore Changing a Rank of a Document by Applying a Rank Transition Function, a method for detecting and mitigating rank-modifying spam in search engine results.

Presenting Search Result Information describes a system and method for presenting search results to a user. The system uses web notebooks to organise and rank search results, incorporating snippets and allowing users to create and manage their own notebooks. This US patent application describes a system and method for presenting search results to a user. The system uses web notebooks to organise and rank search results, incorporating snippets and allowing users to create and manage their own notebooks.
