Thanks for your help.
Converting tags to gene names in GPL9115
I have downloaded GSE31617 data. As you can see its platform is GPL9115.
In mRNA files, there are three columns:
Tag CopyNumber TPM(Transcript Per Million)
CATGTGGATGGGCTTCTTGTA 2 0.23
CATGGGGCCTTCCAGACCCAC 2 0.23
CATGTGCATTTTCAAGTGGGT 2 0.23
CATGAGCCACCGCGCCCTGTC 2 0.23
CATGGAACTAATTCGCTGACC 2 0.23
CATGCTGCTTCGGCCCCAGCG 2 0.23
CATGGTCCTCACCCAAGCCTA 2 0.23
CATGTCTGTGTGTGGTGAGCA 2 0.23
How can I map Tag to RefSeq ID or gene symbol? My goal is making a matrix of expression profile.
Unfortunately, I did not find any useful information in GPL9115. SOFT formatted family file(s) in this page contains something like above columns for all of the available samples in GEO.
I appreciated it if anyone could help me.

You did not read http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM785379 ?
You should align the short tags to the genome using a (very) short read aligner, then overlap the alignments with the genome annotation as in a standard RNA-seq pipeline.
