citation parsing

neda65

hi

I would like to citation  analysis and of each string citation the name of author, title, date, etc. to pay.
But I do not know from what operators and how do I use.
I got used to extract information  operator, but only the first string is extracted from the file.
Help me please

Hi neda,

 

can you get the citation as bibtex and use Read BibTex?

I have a file with this content

(<author> A. Cau, R. Kuiper, and W.-P. de Roever. </author> <title> Formalising Dijkstra's development strategy within Stark's formalism. </title> <editor> In C. B. Jones, R. C. Shaw, and T. Denvir, editors, </editor> <booktitle> Proc. 5th. BCS-FACS Refinement Workshop, </booktitle> <date> 1992. </date><author> M. Kitsuregawa, H. Tanaka, and T. Moto-oka. )

Of course this is a big file and i have use svm and crf for Assessment file And to compare the two methods together.
But do not know how to do that !!!!!

Dear Neda,

 

your file format is very similar to XML. if you replace the first ( with <xml> and the last ) with </xml> it might be possible to read it in. However your posted file has the problem, that there are two authors. This is of course a bit strange.

 

Another way to read it in would be a parsing in RM. Please have a look at the attached process. You can built similar things with the Process Documents from Files operator to parse all your files.

Dear Neda,

 

are you referring to a struct SVM: https://www.cs.cornell.edu/people/tj/svm_light/svm_struct.html ? If so you really take out the big guns first. The struct svm is possibly the most complex solution you could think about.

 

I know that Katharina Morik from the CS chair in dortmund had some eye on the topic, but I think there is no integration into RM yet. You would need to integrate it using Java yourself.
