similar to: Facing problem while compiling on os x 10.10

Hello Everyone, I am a second year graduate student at IIIT-Bangalore and my interest is in the field of Information Retrieval. I have successfully compiled Xapian from source and have implemented some examples. While going through the project list Weighting Schemes project is the one I was looking to contribute to. So i went through the xapian-core/weight where most of the schemes are already

Hi, I'm new to Xapian and wanted to know if it has a specific feature. I want to be able to check the relation between two terms on a page based on how close they are together on the page. I want to use a combination of n-gram based labeling and the "slop" feature found in Elasticsearch. Does Xapian have this/a similar feature? I haven't been able to find any programs that have

Dear Sir, I'm doing a literature survey on search engines. As Xapian is open source, I think I can get the information required by me.  I assume that your system builds a list of keywords and tags to every keyword the documents where it can be found. My questions are as follows: 1. What is the search algorithm used for searching the list of keywords that your search engine has?. Is it the

This might be a little late but I was engaged in my university examinations. Moreover, I have an exam even today so apologies for the delay. Also, I had to change my project from weighting schemes to improve to improve estimated total number of results as weighting schemes was demanding a lot of time going through it. I would really appreciate if you could review my proposal asap.

All, I'm having some issues compiling omega. Here are the particulars I'm on win7, using cygwin 4.9.2 64 bit. Here's the relevant output from make: libtool: link: g++ -fshow-column -Wall -W -Wredundant-decls -Wpointer-arith -Wca st-qual -Wcast-align -Wno-long-long -Wformat-security -fno-gnu-keywords -Wundef -Woverloaded-virtual -Wstrict-null-sentinel -Wshadow -Wstrict-overflow=1

All, I'm trying to compile xapian core and bindings under cygwin. I have no issues running the configure script and then compiling core, but bindings is giving me some issues. I'm running the configure script for bindings as follows: in xapian-bindings-1.4.0 directory. ./configure XAPIAN_CONFIG=/home/John/xapian-core-1.4.0 --with-java and had two issues. The first I solved by doing

Hello, My name is Prakhar Pratyush. I am a 4th year Electronics & Communication engineering undergraduate student at Indian Institute of Technology (IIT) Roorkee. My primary areas of Interest are machine learning, and Information Security and I am proficient in C++/Python/JavaScript programming languages as well. I was looking into the past gsoc organizations, and I came across Xapian. I

Xapian is in the process of joining the Software Freedom Conservancy (https://sfconservancy.org/), but one thing we need to sort out before we can finalise this is some sort of more formal project leadership structure. James Aylett and I have discussed this with Bradley Kuhn from Conservancy, and we think the most appropriate model currently would be a small group of at least 3 (to avoid deadlock

I am using Xapian as the search engine in Hyperkitty for GNU Mailman 3. Is there a page of instructions for end users on the search syntax, such as wildcards and boolean searches? My end users would appreciate such a thing. I am unable to find anything like this. Andrew Bernard

Hi, In my explorations of Omega codebase, I have found that Omega is currently missing support for newer weighting schemes added in 1.4.1 (BM25+, PL2+, Dir+). I'd submit a PR addressing that but as I think I might be missing something so just wanted to check if there's a particular reason for that? P.S. Finally back after a long week. Been eagerly waiting for a weekend since the

Only major performance constraint would be on the training step in the implementation. Although, SDBN has a

Dear Members of Xapian Project, Sorry for troubling you this time. This is Miao LIU, a postgraduate student working on information retrieval system related areas. I have been using Xapian (https://xapian.org) for quite a few months as the database and the searching engine in my IR system. I am currently facing a tough problem that I'd like to put all my posting lists in memory of my

Hi, Now that the clickstream logging PR (#161) is close to getting merged I'm starting to move onto the next step i.e. the implementation of DBN click model for which I think it'd be best to discuss the approach that I intend to take and the classes required. I'm thinking of starting with the implementation of a base class Model to enable the implementation of DBN click model as its

Hi, I am currently pursuing my computing science bachelors degree at university of Alberta, Canada. My speciality lie in Information retrieval, machine learning and data mining. In order to get hands on experience with real world information retrieval systems, I would like to contribute to the Xapian project. I have been going through some of the project ideas in
