    Coherent development depends on following widely used standards that respect our vast legacy of existing entries in the geoscience record. Middleware ensures that we see a coherent view from our desktops of diverse sources of information. Developments specific to managing the written word, map content, and structured data come together in shared metadata linking topics and information types

    Math Search for the Masses: Multimodal Search Interfaces and Appearance-Based Retrieval

    Full text link
    We summarize math search engines and search interfaces produced by the Document and Pattern Recognition Lab in recent years, and in particular the min math search interface and the Tangent search engine. Source code for both systems are publicly available. "The Masses" refers to our emphasis on creating systems for mathematical non-experts, who may be looking to define unfamiliar notation, or browse documents based on the visual appearance of formulae rather than their mathematical semantics.Comment: Paper for Invited Talk at 2015 Conference on Intelligent Computer Mathematics (July, Washington DC

    A Contextual Information Retrieval Model based on Influence Diagrams

    International audienceA key challenge in information retrieval is the use of contex- tual evidence within the ad-hoc retrieval. Our contribution is particularly based on the belief that contextual retrieval is a decision-making prob- lem. For this reason we propose to apply influence diagrams witch are an extension of Bayesian networks to such problems, in order to solve the hard problem of user based relevance estimation. The basic underlying idea is to substitute to the traditional relevance function which measures the degree of matching document-query, a function indexed by the user. In our approach, the user profile is represented by his long term interests. In order to validate our model, we propose furthermore a novel evaluation protocol suitable for the contextual retrieval task. The test collection is an expansion of the standard TREC test data, obtained using a learning scenario of the user's interests. The experimental results show that our model is promising

    A Dynamic Knowledge Management Framework for the High Value Manufacturing Industry

    Dynamic Knowledge Management (KM) is a combination of cultural and technological factors, including the cultural factors of people and their motivations, technological factors of content and infrastructure and, where these both come together, interface factors. In this paper a Dynamic KM framework is described in the context of employees being motivated to create profit for their company through product development in high value manufacturing. It is reported how the framework was discussed during a meeting of the collaborating company’s (BAE Systems) project stakeholders. Participants agreed the framework would have most benefit at the start of the product lifecycle before key decisions were made. The framework has been designed to support organisational learning and to reward employees that improve the position of the company in the market place
