Topic modelling techniques such as LDA have recently been applied to speech transcripts and OCR output. These corpora may contain noisy or erroneous texts which may undermine topic stability. Therefore, it is important to know how well a topic modelling algorithm will perform when applied to noisy data. In this paper we show that different types of textual noise will have diverse effects on the stability of different topic models. From these observations, we propose guidelines for text corpusarXiv:1508.01067v1 fatcat:thskdjuh7jcpli7jl7kzke46ra

We describe a novel document summarization technique that uses informational cues, such as social bookmarks or search queries, as the basis for summary construction by leveraging the snippet-generation capabilities of standard search engines. A comprehensive evaluation demonstrates how the social summarization technique can generate summaries that are of significantly higher quality that those produced by a number of leading alternatives.doi:10.1145/1216295.1216311 dblp:conf/iui/BoydellS07 fatcat:pbzr5zlturcabgrf4a5bi72we4
Speech audio often encapsulates huge volumes of information which traditionally has been challenging to mine and analyse using automated methods. For example, call centres often handle many simultaneous telephone conversations between customers and call centre agents where, apart from relying on limited manual reporting by individual call centre agents, the content, themes and topics of the conversations are not analysed in any depth. In recent years there have been significant improvements indoi:10.1109/bigdataservice.2016.23 dblp:conf/bigdataservice/SuB16 fatcat:dmc7nqywm5awvmqtlgxtrzrzp4

We introduce Topi-cListener, which combines advanced topic modelling techniques with automatic speech transcription to identify key themes and topics across large volumes of recorded audio conversions as well as providing a novel means to explore and visualise the correlation and evolution of topics over time.
Search engines continue to struggle with the challenges presented by Web search: vague queries, impatient users and an enormous and rapidly expanding collection of unmoderated, heterogeneous documents all make for an extremely hostile search environment. In this paper we argue that conventional approaches to Web search -those that adopt a traditional, document-centric, information retrieval perspective -are limited by their refusal to consider the past search behaviour of users during futuredoi:10.1007/s11257-004-5270-4 fatcat:wn5k3suujnb7tkn2ngl2tzfyda

In particular, we argue that in many circumstances the search behaviour of users is repetitive and regular; the same sort of queries tend to recur and the same type of results are often selected. We describe how this observation can lead to a novel approach to a more adaptive form of search, one that leverages past search behaviours as a means to re-rank future search results in a way that recognises the implicit preferences of communities of searchers. We describe and evaluate the I-SPY search engine, which implements this approach to collaborative, community-based search. We show that it offers potential improvements in search performance, especially in certain situations where communities of searchers share similar information needs and use similar queries to express these needs. We also show that I-SPY benefits from important advantages when it comes to user privacy. In short, we argue that I-SPY strikes a useful balance between search personalization and user privacy, by offering a unique form of anonymous personalization, and in doing so may very well provide privacy-conscious Web users with an acceptable approach to personalized search. and after working in industry he has recently returned for take up a research position in the I-SPY group. Oisin's research focuses on the use of relevance feedback techniques in Web search.
We describe and evaluate an approach to personalizing Web search that involves post-processing the results returned by some underlying search engine so that they reflect the interests of a community of like-minded searchers. To do this we leverage the search experiences of the community by mining the title and snippet texts of results that have been selected by community members in response to their queries. Our approach seeks to build a community-based snippet index that reflects the evolvingdoi:10.1145/1148170.1148283 dblp:conf/sigir/BoydellS06 fatcat:4j2z5xgisbakvprm2ad7wieqxa

The I-SPY meta-search engine uses a technique called collaborative Web search to leverage the past search behaviour (queries and selections) of a community of users in order to promote search results that are relevant to the community. In this paper we describe recent studies to clarify the benefits of this approach in situations when the behaviour of users cannot be relied upon in terms of their ability to consistently select relevant results during search sessions.doi:10.1145/1076034.1076143 dblp:conf/sigir/BoydellSGS05 fatcat:rbycrrad7jan7dc6lommfuxika
Current malware detection and classification approaches generally rely on time consuming and knowledge intensive processes to extract patterns (signatures) and behaviors from malware, which are then used for identification. Moreover, these signatures are often limited to local, contiguous sequences within the data whilst ignoring their context in relation to each other and throughout the malware file as a whole. We present a Deep Learning based malware classification approach that requires nodoi:10.1016/j.diin.2018.04.024 fatcat:aulmxt3mcvgddcxjqfycdzvanm
