I don't know about that.
Information theory is about the 3 c's :
Compression, Correction, and Cryptography.
Compression is about abbreviating a message to make it as efficient as possible to get across a telephone wire or some other channel. Like how to compress a CD audio track into an MP3 so you can upload it.
Correction is about error correction and checksums to make sure the MP3 is put back together again properly. By the way, almost all transmission methods have loss, and are considered "noisy channels". The goal is a perfect message across and imperfect medium.
Cryptography is about encoding and decoding for security.
These all have to do with treating data as signals or symbols and seeing what you can do with those symbols in each of these realms. It doesn't matter what song the MP3 stores, and likewise, Information Theory is not concerned with any of the meanings in the compressed, corrected or encrypted data.
So, even though "Information" is in the title, it isn't about meaning.
Look up Claude Shannon, who is considered the father of Information Theory. The question was put to him by industry how much telephone wire they should install to do what they needed it to do, but have enough bandwidth so they wouldn't have to re-install the wire anytime soon. And he spawned an entire branch of mathematics that gave us the digital age.
