From its creation, AxIS has developed several softwares validated experimentally on various applications (in Java, C++ or/and Perl):
Data Mining and Web Usage Mining
- Two Methods for Extracting Sequential Patterns with Low Support
- SMDS, a clustering method for mining sequential patterns in data streams
- ATWUEDA (Axis Tool for Web Usage Evolving Data Analysis)
- Clustering and Classification Toolbox (intranet access On-line Tools )
- The SODAS 2 software
Building Recommender Systems (Java)
- CBR*Tools, an Object-Oriented Software Library for Case-Based Reasoning
- Broadway*Tools: a library based on CBR*Tools and on our recommendation computation approach called the "Broawday approach". Broadway*tools supports the designer in developping Broadway-based systems for supporting information retrieval on the web or inside a Web site.
- K-MADe, Kernel of Model for Activity Description environment
- CLF for generating efficient parsers
- Bibadminfor the management of a collection of publications
- QSOS-based OI Grid for supporting the OI tool selection
- NiceAir, An Android mock-up for visualizing air quality on Google map in Nice
AWLH (AxIS Web Log Preprocessing and Data Stream extraction). for Web Usage Mining (WUM). In the context of the Eiffel project (2008-2009), we isolated and redesigned the core of AxISlogMiner preprocessing tool (we called it AWLH) composed of a set of tools for pre-processing Web log files. AWLH can extract and structure log files from several Web servers using different input format. The Web log files are cleaned as usually before to be used by data mining methods, as they contain many noisy entries (for example, robots bring a lot of noise in the analysis of user behaviour then it is important in this case to identify robot requests). The data are stored within a database whose model has been improved.
Now the current version of our Web log processing offers:
- Processing of several log files from several servers,
- Support of several input formats (CLF, ECLF, IIS, custom, etc.);
- Incremental pre-processing;
- Java API to help integration of AWLH in external application.

ATWUEDA for Web Usage Evolving Data Analysis was developed by A. Da Silva in her thesis. This tool was developed in Java and uses the JRI library in order to allow the application of R functions in the Java environment. R is a programming language and software environment for statistical computing (R-project). ATWUEDA is able to read data from a cross table in a MySQL database, split the data according to the user specifications (in logical or temporal windows) and then apply the approach proposed in the Da Silva's thesis in order to detect changes in dynamic environment. The proposed approach characterizes the changes undergone by the usage groups (e.g. appearance, disappearance, fusion and split) at each timestamp. Graphics 26 are generated for each analyzed window, exhibiting statistics that characterizes changing points over time.

An Object-Oriented Software Library for Case-Based Reasoning
CBR*Tools is an object-oriented software library for Case-Based Reasoning (CBR). It provides a basic reusable CBR framework that supports the development of CBR applications. It can be especially used for problems addressing behavorial situation retrieval and indexation.
CBR*Tools consists of three packages, namely, the core, time, and navigation package. The library is specified with the UMT notation (Rose Rational) and written in Java. Click on the icon (on the right hand side), to get a full image of the system's main user interface.
Case-Based Systems For Supporting User Navigation and Information retrieval on Internet.
- Plant nutrition control in collaboration with INRA Sophia-Antipolis.
- Navigation on internet : BROADWAY-Web (ex Broawday-V1) is a case-based system for supporting navigation on internet which is based on the http server called Jigsaw (W3C) (written in Java) and the CBR*Tools library. The first version of BROADWAY-Web will be avalaible soon.<
- Argumentation in collective decision making (see ICCBR'97 on HERMES)
- Query reformulation > in the context of a meta search engine in collaborationn with XRCE : BeCBKB
- e-behaviour project (2001-2003) (INRIA & UNSA): supporting navigation inside INRIA RA clone site (2001). Reuse of past visual and non visual behaviours. Visual data are issued from a eye tracking system.
- Others applications for supporting Navigation inside a Web site (BROADWAY-PREDICT))
Some information about our first Broadway-based application : Broadway-Web
Broadway-Web is a WWW browsing advisor reusing past navigations from a group of users : it follows a gorup of users during their navigations on the WWW (proxy-based architecture) and advise them by displaying a list of potentially relevant documents to visit next. Click on the icon (on the right hand side), to get a full image of the system's main user interface. Broadway uses case-based reasoning to reuse precise experiences derived from past navigations with a time-extended situation assessment : the advice are based mainly on similarity of ordered sequence of past accessed documents. In addition, the dynamic of the WWW is addresses in the reuse step and with a specific method for case forgetting.
Broadway-Web is written in Java using the Jigsaw proxy (W3C consortium) and CBR*Tools. It will be soon running on the Web. Click here for the slides of UK-CBR97 presentation.

http://www.info.fundp. ac.be/asso/sodaslink.htm. See 2009 AxIS annual report for more details of the main contributions of AxIS to SODAS ,  which have been registered at APP.
- a java library (the somlib) that provides efficient implementations of several SOM variants, especially those that can handle dissimilarity data (available on Inria's Gforge server http://gforge.inria.fr/projects/somlib/, developed by AxIS Rocquencourt and Brieuc Conan-Guez from Universite de Metz).
- a functional Multi-Layer Perceptron library, called FNET, that implements in C++ supervised classification of functional data (developed by AxIS Rocquencourt).
- two partitionning clustering methods on the dissimilarity tables issued from a collaboration between AxIS Rocquencourt team and Recife University, Brazil: CDis and CCClust. Both are written in C++ and use the SOL developed for SODAS.
- two improved and standalone versions of SODAS modules, SCluster and DIVCLUST (AxIS Rocquencourt).
- a java implementation of the 2-3 AHC (developed by AxIS Sophia Antipolis). The software is available as a Java applet which runs the hierarchies visualisation toolbox called HCT for Hierarchical Clustering Toolbox).

QSOS-based OI Grid for supporting the OI tool selection
QSOS-based OI Grid for supporting the OI tool selection. The QSOS Grid to compare OI Tools, which is in an XML format, has been translated into a MindMap (see http://ictusagelab.inria.fr/IDEASTREAM/node/12). As a first mock-up, the QSOS Web Interface O3S will be installed in september 2011 on our server For the future, we will extend our own QSOS comparative method to other softwares and to other categories interesting for our Living Lab community
NiceAir, an android mock-up for visualizing air quality data on Google map in Nice as well as some interests points (free bikes, free places, bus stop, etc.). Such a mockup will be experimented in the co-creation of green services in the Elliot project and during the european Mobility Week.
