This article describes the process of designing a hybrid decision support system HSWD for the Fire Service. This designing process realize a methodology of design for trustworthy software – DFTS. In this article describes chosen project problems and their solution on the first stage of proposed design process.

This paper proposes application of Formal Concept Analysis (FCA) in creating character-level information extraction patterns and presents BigGrams: a prototype of a languageindependent information extraction system. The main goal of the system is to recognise and to extract of named entities belonging to some semantic classes (e.g. cars, actors, pop-stars, etc.) from semi structured text (web page documents).

This article describes the author’s classification of the methods and techniques of textual data mining. In this article also describes the currently available methods and sauces representation of textual data and their processing techniques. Also conducted a discussion on the processing of text documents using the presented methods. This paper also discussed the possibilities and limitations of individual methods to process the presented text documents.

The article „Proposition of hybrid process model semi structured description of event from fire services rescues operation” describes a review of actual developed knowledge representation and case representation for fire services cases based reasoning system. The article also describes a method of processing the cases of events. This processing method based on classification and information retrieval.

Few days ago a SIMIS magazine publicated my article Crowdsourcing in rescue fire service – proposed application. In this article I describes the proposal to apply crowdsourcing in Polish rescue fire service. This article also describes basic principles for implementing an crowdsourcing information platform in rescue fire service as well as the scheme of its implementation. Of this paper also to I describes the genesis of this proposal related to the evaluation of research conducted by the author on text mining analysis and extraction of information in the design of information systems.

Few days ago I had a installation problem package revoIPC 1.0-3 and doSMP 1.0.1. When I was compiled revoIPC 1.0-3, compilator returned this error:
g++ -I/usr/local/lib64/R/include -I/usr/local/include -I . -fpic
-g -O2 -c interface.cc -o interface.o
In file included from ./boost/interprocess/detail/
Rich Calaway from revolutionanalytics.com helped me quickly and sent solution. The patch with fix this problem is a:
„… go to src/boost/interprocess/detail/iterators.hpp and comment out lines 341-353”
Thanks for this advice we can compile revoIPC 1.0-3 and use it in with doSMP 1.0.1. Just one thinks, if we use doSMP 1.0.1 in new revoIPC 1.0-4 and we try execute this program:
rmSessions(all.names = TRUE)
w <- startWorkers(2)
registerDoSMP(w)
foreach(i=1:3) %dopar% sqrt(i)
R return this error:
> foreach(i=1:3) %dopar% sqrt(i) *** caught segfault ***
address 0x7fd0e562f58c, cause ‚memory not mapped’ Traceback:
1: .Call(„returnResult”, q, t$task, serialize(res, NULL))
2: ipcTaskReturnResult(taskq, taskchunk, resultchunk)
3: doSMP:::workerLoop(qname, rank, verbose, out)
aborting …
Rich Calaway helped me fixed this problem to. I don’t check it but if someone want to use revoIPC 1.0-4 must:
„… remove the PKG_CPPFLAGS=-DNDEBUG line from Makevars.in in the src directory.”
Good luck.

For few mounth I created a data mining review – „Data mining review and use’s classification, methods and techniques”. This article can finds in Studia i Materiały Informatyki Stosowanej (SIMIS, http://www.simis.ukw.edu.pl/) if he will favourably reviews. Below I represended abstract of this paper:
The large quantity of the data and information accumulated into actual information systems and their successive extension extorted the development of new processes, techniques and methods to their storing, processing and analysing. Currently the achievement from the statistical analyses and artificial intelligence area are use to the analysis process of the large data sets. These fields make up the core of data exploration – data mining. Currently the data mining aspires to independent scientific method which one uses to solving problems from range of information analysis comes from the data bases menagments systems. In this article was described review and use’s classification, methods and techniques which they are using in the process of the data exploration. In this article also was described actual development direction and described elements which require this young applied discipline of the science.

I finished implementation a questionnaire for fire service on the previous day. This questionnaire was implemented for quantitative/qualitative research. The destination of this research is a creation a hybrid decision support system for Polish fire service. It’s a complicate problem which require many of different researches. This research integrate solution from logistic, transport, game theory, artificial intelligence, linguistics, retrieval of text information like a text mining and especially text reprezentation and his processing. All project was described by process of design for trustworthy software (DFTS). The results of investigations will be published after the completion questionnaire by respondenst.
Questionnaire was implemented using web technologies like a JAVA+JSF+Hibernate+MySQL.
