Probabilistic Methods for Microarray Data Analysis (PMMA)
Period: 1/2004-12/2005
Researchers: Petri Myllymäki, Jorma Rissanen, Teemu Roos, Hannes Wettig, Jussi Lahtinen, Tomi Silander
Funding: Tekes
The goal of this project is to develop new probabilistic methods for analysis of micro chip data. The research especially focuses on the following sub-areas: removing noise from micro chip images, developing compression estimations (comprestimation) methods, grouping and classification of genes, building gene regulation networks and evaluation of results. The research consortium consists of three sub-groups: 1) the Laboratory for Computational Engineering, Helsinki University of Technology (director Jukka Heinnonen, DSc (Tech)), 2) the Institute of Biomedicine, University of Helsinki (director Professor Tomi Mäkelä) and 3) Department of Computer Science, University of Helsinki (director Professor Petri Myllymäki).
In 2005, the project developed a new kind of image noise-removal method based on soft thresholding. In addition, a distributed version of the project’s Bayesian web tool (B-Course) was developed for the analysis of even larger data sets than before.
National Semantic Web Ontology Project in Finland (FinnONTO)

The project develops a basis for the infrastructure for a Finnish semantic web including ontologies and meta-data formats, ontology services, and the tools and processes involved.
For the ontology part, the project has developed the general Finnish ontology YSO, based on the Finnish terminology ontology YSA, as well as several other ontologies. The use of ontologies enable more efficient use of valuable data contents over data networks. For the ontology service part, the project develops the ontology library server ONKI and its web services for the distributed utilisation and development of a nationally significant semantic web. The goal is to move from present-day key word methods towards using the semantically more fruitful ontology techniques for indexing and search functions. This will enable more user-friendly and exact information retrieval, the semantic interoperability of data systems and intelligent services on the Web. The technology is applied in concrete case applications. These include the MuseoSuomi (MuseumFinland) system in the area of museums, the semantic publishing platform of Finnish culture KulttuuriSampo that will be the developed from it, a portal for promoting national health, a meta-search engine and Q/A system for libraries, and semantic portal for the educational field.

Intelligent Web Services (IWebS)
Period: 8/2003-7/2005
Researchers: Eero Hyvönen, Markus Holi, Mikko Laukkanen, Petri Lindgren, Eetu Mäkelä, Samppa Saarela, Teemu Sidoroff, Kim Viljanen
Funding: Fonecta Oy, Stakes, Tekes, TeliaSonera Finland Oyj, TietoEnator Oyj, Ministry of Finances
The project developed the technology of the semantic web and web services for intelligent yellow-pages-like services and semantic portals.
The results of the project include a model for the semantic description of services, several ontologies needed to describe services and the OntoViews tool for developing semantic portals. The technology was utilised in three pilot projects. In the area of eCommerce, the project produced the application prototype Veturi, a yellow-pages-like product and service index, which is based on the Fonecta Oy 020202.fi service index. In the area of eGovernment, semantic portals were the main object of research and development. The project developed a semantic prototype of the Suomi.fi portal of the Ministry of Finances to utilise ontology-based multi-display searching and the automatic connecting of heterogeneic data contents produced by different organisations with the help of logical inference. In the field of eHealth the project studied ontology technologies mainly for the description of health services for the elderly. Some public health services were put into ontological form and connected to the yellow-pages material of the Veturi portal.
