Hi Anders, Here are some brief answers. Good luck with your research. Anders Koed Madsen wrote: [snip]
Before making a final decision on which crawler to use I just wanted to know whether anyone of you have opinions about the the Issue-crawler in comparison to SoSciBot (http://socscibot.wlv.ac.uk/) and VOSON (http://voson.anu.edu.au/) or other crawlers. So:
- What are the pro and cons of the different software-packages? As I mentioned off-list to you just now, I'm not the best person to comment here but I'd be keen to know if anyone has done a comparison.
- Does any of them allow for detecting the timestamp of the link (when is it placed)? Or do you know of any crawlers that do that? VOSON doesn't do this. I don't think a crawler can collect this data, but I could be wrong. I think the best you can do is infer date of link creation by comparing across the panels you plan to create e.g. if link from i to j that is present at time t wasn't present in time t-1, then it was created between t and t-1.
- Can the results of SoSciBot and VOSON be exported into UCI-net as well (I haven´t been able to figure that out from the sites)? I'm not sure about SocSciBot (but can imagine it would) but with VOSON, the answer is yes. In VOSON there is a facility to export the hyperlink network in pajek format and my understanding is that format can be read into UCInet.
All the best,
