OK – I hadn’t looked at the Citeseer search page. You won’t get any results from a “standard” DA search set that queries the URL page itself, because the query isn’t fed to Citeseer’s search engine.
To do that, one needs to write a special plugin that will communicate with Citeseer’s search engine. There’s an introduction to writing DA plugins in the user documentation.
DEVONagent already includes a number of plugins, one of which is for Citeseer.
So I created a new Search Set and checked the Citeseer plugin for it. Result: no results for a search for the string "amorphous silicon hydrogenated ". What happened? I’m not sure, but in checking a few pages on the Citeseer site it appears they have been doing some housekeeping, resulting in redirection of previously linked pages. Perhaps the supplied Citeseer plugin will need to be updated as a result.
Frustrated by my attempt to find literature pertaining to “amorphous silicon hydrogenated” I then checked the plugin for Google on that new search set. Just for the heck of it, I instructed DEVONagent to follow links one level down.
Now, although the search takes a while on my satellite Internet connection, DEVONagent has downloaded to my computer a treasure trove of literature on the topic. I’ve got not just the 8 results found by Citeseeker directly, but 479 documents ranging from abstracts to papers, articles, patents and books. DEVONagent has prepared a summary of each document, a list of “topic” terms and will display a graphical depiction of term usage for each “topic”. So if I’m interested in chemical or physical properties, techniques for deposition of thin films and so on I can explore this collection of references with some assistance.
If I wish I can dump that collection to my Archive, or to a DEVONthink Pro database. Or I can instruct that search set to run periodically and inform me just of new literature that has appeared since the last search run, perhaps by sending me an email listing the new results.
Since I had told DEVONagent’s search set to ask Google for items related to my query, why didn’t I just ask Google in the first place? Here’s why: Google will provide a list of 754,000 page references (at the moment I looked), not the pages themselves. DEVONagent has selected 479 of those, downloaded them to my computer and provided a summary of each document together with some analysis to the words used in the collection.
