INFORMATION RETRIEVAL - 2019/0
Module code: COM2034
This module will provide students with an understanding of information retrieval. This relates to multimedia data (principally text, but also image, video and audio) stored for, presented on, and consumed from, the web amongst other sources. The module covers fundamental techniques and strategies of information retrieval used in a variety of online applications such as web-search engines, document matching systems, and business storage and analytics.

· Spiders/crawlers, stopwords and keywords, indexing and stemming.
· Boolean retrieval, ranked retrieval, and vector spaces
· Query expansion and its relationship with the Semantic Web.
· Assessing relevance - precision and recall
· Metadata and semantics.
· Databases, data normalization and de-normalization.
· The challenges presented by “Big Data”
· NoSQL and Cloud Computing for distributed and scalable treatment of “Big Data”.

The assessment strategy is designed to provide students with the opportunity to demonstrate :
Explaining theories behind search and assess the impacts on search performance inherent in variations in their construction
Elaborating a range of techniques for analysing, modelling, and retrieving text documents
Contrasting different kinds of applications, and their integration, in satisfying specific user information needs
Elaborating, contrasting and evaluating information models that support efficient storage, retrieval and browsing, in a variety of applications.
Contrasting the need for efficiency of data storage with the needs of batch access to large datasets.
Applying appropriate, standard, metadata sets and semantics to ensure effective data storage and curation.
Identifying the important features for storage, retrieval and browsing of non-textual data
Thus, the summative assessment for this module consists of:
A coursework that will involve applying and evaluating various concepts and principles introduced in lectures and tested in lab sessions. Specific software and analytical approaches will be explored in these assessments. Submissions will be made through the VLE, with the deadline towards the end of the module. The coursework may assess against all relevant learning outcomes addressed suitably in advance of the deadline.
2-hour written unseen written examination comprising a mixture of short answer and discussion questions. The examination paper may assess against all learning outcomes.
Formative assessment and feedback
Students will be progressively completing structured lab workbooks where submission of each is necessary to progress to the next. On submission, informative solutions are also provided such that students will be able to gauge their progress as the module progresses.
- Help students to gain an understanding of the current study of information retrieval
- Provide practical understanding of how data are represented for storage, analysis and use in particular applications.

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
Develop an understanding for the principles and role of information retrieval and closely related applications
The learning and teaching methods include:
· Lectures, including case studies•
· Occasional set reading•
· In-class discussions
· In-class and out-of-class exercises•
· Lab sessions•
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
