Solution Overview

Problem

Conversational interfaces often fail to provide a dynamic and believable experience for users as they are typically associated with a single personality, lacking the ability to adapt to the lexical personality and preferences of individual users.

Innovation Solution

The system analyzes user inputs to determine their lexical personality through characteristics like formality, politeness, and accent, and uses a repository of synonym tokens with associated scores to generate personalized responses, and also utilizes social network information to identify personas that match user profiles, modifying responses to align with user preferences and social interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conversational interface uses a single fixed personality for all interactions, then the system complexity is low and implementation is simple, but the adaptability to different user preferences and the believability of interactions deteriorates

Engineering Contradiction:
Improveadaptability to user lexical personalityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The conversational interface dynamically adapts its lexical personality based on the detected personality of the user's input. The system analyzes characteristics such as formality, politeness, and accent in the user's input and selects or generates responses with matching lexical personality scores, transforming a static single-personality system into a dynamic multi-personality system that adapts in real-time

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes lexical personality parameters (formality, politeness, accent scores) of the response based on the detected parameters of the user's input. By analyzing and matching these linguistic parameters, the system selects appropriate synonym tokens with corresponding personality scores to generate responses that align with the user's lexical personality

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the conversational interface analyzes lexical personality and uses synonym replacement, then the personalization and user engagement improve, but the processing time and computational complexity increase

Engineering Contradiction:
Improveuser engagementVSAvoidresponse generation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of the user's input to detect lexical personality characteristics (formality, politeness, accent) before generating the response. By detecting these parameters early in the processing pipeline, the system can efficiently select appropriate synonym tokens and generate personalized responses without adding significant delay to the overall interaction

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If the system uses a repository of synonym tokens with lexical personality scores, then the precision of personality matching improves, but the memory requirements and data structure complexity increase

Engineering Contradiction:
Improvepersonality score matching precisionVSAvoidrepository data volume
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The synonym repository organizes tokens with specific lexical personality scores (formality, politeness, accent) to enable precise matching for different local personality dimensions. Rather than using a single generic synonym list, the system maintains structured repositories that allow selective retrieval of synonyms with appropriate personality characteristics for each specific matching dimension

Inventive Principle:
Principle #3Local quality

AI summary

The present disclosure involves systems, software, and computer implemented methods for personalizing interactions within a conversational interface based on an input context. One example system performs operations including receiving a conversational input received via a conversational interface. The conversational input is analyzed to determine an intent and lexical personality score based on the input's characteristics. A set of responsive content is determined and includes a set of initial tokens representing an initial response. A set of synonym tokens associated with at least some of the initial tokens are identified, and at least one synonym token associated with a similar lexical personality score to the input is determined. At least one of the initial tokens are replaced with the determined synonym token to generate a modified version of the set of response content. The modified version of the response is then transmitted to a device in response to the input.
