This module is designed to recognize and extract entities from text, such as user names and token symbols.
It leverages OpenAI's API to process text and identify these entities.
Contracts Involved:
Alias Contract: This smart contract holds mappings of aliases to addresses. It helps in identifying and verifying users.
Example: AliasContract might map "Alice" to a specific blockchain address.
Token Information Contract: This smart contract holds the token symbols and names. It helps in identifying and verifying tokens.
Example: TokenInfoContract might map "ETH" to "Ethereum".
Workflow:
Entity Recognition: The NER module processes input text to identify entities such as user names and token symbols.
API Calls: The system makes function calls to the smart contracts to retrieve the necessary information.
For a user alias, it queries the AliasContract to get the corresponding address.
For a token symbol, it queries the TokenInfoContract to get the full token name and additional details.
Output: The system combines the information from the NER module and the smart contracts to identify and verify users and tokens accurately.
Example Workflow
Input Text: "Alice sent 10 ETH"
NER Module:
Identifies "Alice" as a user alias.
Identifies "ETH" as a token symbol.
API Function Calls:
Calls AliasContract with "Alice" to get the blockchain address.
Calls TokenInfoContract with "ETH" to get the token details (e.g., "Ethereum").
Output:
User: Alice -> Address: 0x123...
Token: ETH -> Ethereum
Smart Contract Interfaces
Here’s an example of what the smart contract interfaces might look like in Solidity:
// AliasContract.sol
pragma solidity ^0.8.0;
contract AliasContract {
mapping(string => address) private aliases;
// Add or update alias
function setAlias(string memory alias, address addr) public {
aliases[alias] = addr;
}
// Retrieve address by alias
function getAddressByAlias(string memory alias) public view returns (address) {
return aliases[alias];
}
}
// TokenInfoContract.sol
pragma solidity ^0.8.0;
contract TokenInfoContract {
struct TokenInfo {
string name;
string symbol;
}
mapping(string => TokenInfo) private tokens;
// Add or update token information
function setTokenInfo(string memory symbol, string memory name) public {
tokens[symbol] = TokenInfo(name, symbol);
}
// Retrieve token info by symbol
function getTokenInfoBySymbol(string memory symbol) public view returns (string memory) {
return tokens[symbol].name;
}
}
Integration with OpenAI API
In your backend system, you would integrate the OpenAI API with these contracts to process text input and make the necessary contract calls:
# Pseudo-code for integrating NER and smart contracts
def identify_entities(text):
# Call OpenAI API to identify entities in the text
entities = openai_ner_api(text)
return entities
def get_user_address(alias):
# Call AliasContract to get the address
address = alias_contract.getAddressByAlias(alias)
return address
def get_token_info(symbol):
# Call TokenInfoContract to get the token information
token_name = token_info_contract.getTokenInfoBySymbol(symbol)
return token_name
# Example usage
text = "Alice sent 10 ETH"
entities = identify_entities(text)
user_address = get_user_address(entities['user_alias'])
token_info = get_token_info(entities['token_symbol'])
print(f"User: {entities['user_alias']} -> Address: {user_address}")
print(f"Token: {entities['token_symbol']} -> {token_info}")
This setup ensures that your system can accurately identify and verify users and tokens using the power of NER combined with the reliability of blockchain smart contracts.
