Answer Finding Guided by Question Semantic Constraints

AAAI Conferences

As part of the task of automated question answering from a large collection of text documents, the reduction of the search space to a smaller set of document passages that are actually searched for answers constitutes a difficult but rewarding research issue. We propose a set of precision-enhancing filters for passage retrieval based on semantic constraints detected in the submitted questions. The approach improves the performance of the underlying question answering system in terms of both answer accuracy and time performance.


Ontology-Based Query Expansion with Latently Related Named Entities for Semantic Text Search

arXiv.org Artificial Intelligence

Traditional information retrieval systems represent documents and queries by keyword sets. However, the content of a document or a query is mainly defined by both keywords and named entities occurring in it. Named entities have ontological features, namely, their aliases, classes, and identifiers, which are hidden from their textual appearance. Besides, the meaning of a query may imply latent named entities that are related to the apparent ones in the query. We propose an ontology-based generalized vector space model to semantic text search. It exploits ontological features of named entities and their latently related ones to reveal the semantics of documents and queries. We also propose a framework to combine different ontologies to take their complementary advantages for semantic annotation and searching. Experiments on a benchmark dataset show better search quality of our model to other ones.


Search engine results can now chat to computer users

The Independent - Tech

Microsoft has started testing search engine results that can chat directly to users. The company wants developers to create custom chatbots that can be added to search listings on Bing. Users will be able to ask the bots for basic information about venues such as restaurants and cinemas, such as opening hours and parking information. They're powered by Skype, and the functionality has already been rolled out to a small number of venues, including a restaurant in Seattle called Monsoon. Unfortunately, at the time of publication, the chatbot didn't actually allow me to submit any questions.


iPhone Siri prank tricks people into phoning emergency services

The Independent - Tech

A prank designed to trick iPhone users into calling emergency services is currently spreading online. Owners of Apple products are being encouraged to say '108' to Siri, unaware of the consequences. As 108 is the equivalent of 999 in India, the digital assistant will recognise it as a command to contact emergency services in the phone user's local area.

Amazon Alexa just got a lot more useful for Apple customers

The Independent

You can now link your iCloud Calendar to the Alexa voice assistant. Amazon has just rolled out the functionality to Alexa-compatible devices, describing it as "a top requested feature". The announcement should please iPhone, iPad and Mac users, who can now organise their calendar and quickly find out about their schedule by chatting to Alexa. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.
