Enterprise Modelling, Information Systems, Photo, Presentation, Slides, SYSLAB

Anders Tell from Toolsmiths gave a talk about effective e-tools for business people. Anders Tell has many years of experience of model driven architectures and has been active in several international standardisation organisations. Anders asked the question: Do business analysts, experts and practitioners have access to and knowledge of effective tools and models for carrying out business modeling, architecture, implementation, operations and follow-up? Thanks, Anders, for a thought inspiring seminar!

Presentation on Service Oriented Business Models for ERP

Information Systems, Presentation, Service Science, Slides, SYSLAB

Today I gave a presentation on new business models for service oriented enterprise systems at the ARIS ProcessDays Nordic 2008. The presentation discussed how ERP functionality can be provided through services. New roles will emerge, like the platform provider who will provide support for a network of users and vendors. The audience showed much interest and posed questions about the consequences for ICT departments, whether security will be a problem for the new business models, the impact of open source, and the role of networks.

A new course- Requirements Engineering!

SYSLAB

Requirements Engineering (RE) plays a fundamental role within the systems development process. The goal of this course is to bring in the concepts, methods and techniques needed in the eliciting, analyzing, documenting, validating, and managing requirements for complex information systems. It explains how requirements engineering fits into a broader systems development process, and provides an understanding of the main challenges in requirements engineering nowadays. During this course, you will learn how to:

– Identify stakeholders and their influence on the system requirements.
– Specify functional requirements using different modeling methods.
– Identify and classify and non-functional requirements, influences and constraints.
– Negotiate and prioritize requirements.
– Validate requirements.
– Document and trace requirements using computer-based tools.
– Manage changing requirements and establish traceability of changes.
– Practice the different roles in the requirement engineering process, by working in groups.
– Analyze the practical use of the latest scientific contributions within the RE subject.

Since requirements management is a multidisciplinary field and closely related to areas such as general management, project and product management, product marketing, and industrial design, students from a variety of disciplines can benefit from this course.

New course – Web mining, spring 2009, period 3, 7,5 hp

SYSLAB

Internet contains a huge amount of information, which is rapidly growing at an ever increasing pace. People, organizations and corporations from the whole world are adding different types of information to the web continuously in various languages. The web therefore contains potentially very interesting and valuable information. This course will investigate various techniques for processing the Web in order to extract such information, refine it and make it more structured, thus making it both more valuable and accessible. These techniques are often referred to as web mining techniques.

The domains within the Internet that we will study are databases, e-commerce web sites, wikis, virtual communities and blogs. Semantic web and Web 2.0 are two other concepts that are relevant for the course. Web mining is considered to contain three main areas, namely web content mining, web structure mining and web usage mining. Web structure mining is closely related to information search techniques, and web usage mining to opinion mining or sentiment analysis. Also related is the automatic construction of sociograms. Web content mining can for example be used to find the cheapest airline tickets, by monitoring all web based databases of all airlines in order to attempt to find the lowest common denominator of all databases.
Web mining techniques explored in the course are human language technology, machine learning, statistics, information retrieval and extraction, text mining, text summarization, automatic classification, clustering, wrapper induction, normalization of data, match cardinality of data in different databases, interface matching, schema matching, sentiment analysis, opinion mining, extraction of comparatives, forensic linguistics etc.

NTUA visits SYSLAB

Information Systems, Presentation, Slides, SYSLAB

This Friday, Yannis Charalabidis, George Gionis, Tassos Tsitsanis, and Ourania Markaki from National Technical University of Athens visited us. National Technical University of Athens is one of the oldest, most prestigious and most competitive academic institute in Greece. The Decision Support Systems Laboratory of NTUA has a long and successful tradition in research activities, in the areas of Information Systems, eGovernment, eBusiness, and complex IT project design and evaluation. Yannis and his colleagues gave a presentation of recent work on eBusiness and eGovernment. NTUA has a solid experience in these areas; one example is that NTUA has set up a registry containing more than 1000 public service definitions.

Thanks Yannis, George, Tassos, and Ourania for sharing your experiences!

Guests from Khalifa University

SYSLAB

Today I gave a presentation of the Informations Systems group at ICT school at KTH to two guests from Khalifa University in Sharjah, United Arab Emirates:
Dr. Ali Al-Qayedi and Mr. Salah Al Akbaru.

The slides from the presentation can be found here. They are based on material produced by Lars Asker, Magnus Boman, Mats Danielson, Paul Johannesson and myself. Lasse, Magnus, Mats and Paul, thank you for your contribution.

Seminar on three Human Language Technology research projects here at DSV

Health Informatics, Information Systems, Presentation, SYSLAB

Hercules Dalianis, Sumithra Velupillai and Martin Hassel held a lunch seminar on three Human Language Technology research projects here at DSV.

Hercules presented results from the project Tvärsök which aims to bridge the language gap between the Nordic countries. More specifically, if you search for documents in Swedish you should be able to find corresponding information in Danish or Norwegian if such are lacking for Swedish. The idea is that while you might have active knowledge of Swedish, in the sense that you can formulate search queries in that language, you might still be able to read and comprehend closely related languages even if you cannot effectively formulate queries in those languages (passive knowledge). This work has resulted in new lexical resources in the mobility domain as well as new methods for identifying parallel text [Hercules’ slides]

Sumithra presented ongoing work in the KEA project which concerns the medical domain. In this project we have access to a very large set of medical records, on which we aim to apply an array of text mining techniques. However, these patient files need to be de-identified before they can be exposed to a broader spectrum of researchers. A major part so far has been the development and porting of de-identification methods to Swedish. Parallel tracks are the exposing of relations between loosely defined features hidden in the vast amount of clinical data, as well as the identification of (un)certainty in diagnoses [Sumithra’s slides]

Martin presented two related projects on language technology based services for eGoverment. The first one, IMAIL, which just recently has been approved, concerns the automation of responses to requests sent by e-mail to the Swedish Social Insurance Agency (Försäkringskassan). These requests will be classified as recognised, in which case a predefined response can automatically be sent to the customer, or unrecognised and forwarded to a government official. In the latter case a tool already employed in the KEA project – Infomat – can be adapted to present the official with a view over previous transactions related to incoming request. The second project, still awaiting approval, “Intelligent cross-language services for eGovernment” is a quite ambitious extension to IMAIL which aims at further dealing with translation, multilingual authoring and cross-lingual information extraction for the Swedish minority languages [Martin’s slides]
