Data Collection by Survey

8.7K
The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Methods for Image-based Surveys of Benthic Macroinvertebrates and Their Habitat Exemplified by the Drop Camera Survey for the Atlantic Sea Scallop

10.1K
Image based surveying is an increasingly practical, non-invasive method to sample the marine environment. We present the protocol of a drop camera survey that estimates the abundance and distribution of the Atlantic sea scallop (Placopecten magellanicus). We discuss how this protocol can be generalized for application to other benthic...

Área de la Ciencia:

  • Ciencia de la Nutrición
  • Inteligencia Artificial
  • Ciencia de Datos

Sus antecedentes:

  • Las encuestas dietéticas tradicionales requieren mucha mano de obra y son propensas a imprecisiones.
  • La recopilación precisa de datos nutricionales es crucial para la investigación de la salud pública.
  • Los avances en los modelos de lenguaje grandes (LLM) ofrecen soluciones potenciales para los desafíos de la recopilación de datos.

Objetivo del estudio:

  • Evaluar la efectividad de los LLM en la mejora de la precisión y eficiencia de las encuestas dietéticas.
  • Evaluar el rendimiento de la extracción de datos basada en LLM en comparación con los métodos manuales.

Principales métodos:

  • Se empleó un protocolo de recuerdo dietético de 24 horas con un bolígrafo de grabación inteligente que capturaba datos de audio.
  • Las grabaciones de audio se transcribieron y procesaron utilizando GLM-4 para la ingeniería de indicaciones y el razonamiento de cadena de pensamiento.
  • Se analizó la integridad y consistencia de los datos estructurados generados por LLM, y se calcularon las puntuaciones de precisión y F1.

Principales resultados:

  • Los datos estructurados basados en LLM lograron una tasa de integridad general del 92,5% y una consistencia del 86% con los registros manuales.
  • El LLM demostró una alta precisión en el reconocimiento de ingredientes y ubicaciones de alimentos.
  • El modelo logró un 94% de precisión y una puntuación F1 del 89,7% en el conjunto de datos.

Conclusiones:

  • El reconocimiento de texto y la extracción de datos impulsados por LLM sirven como herramientas valiosas para mejorar la eficiencia y precisión de las encuestas dietéticas.
  • El desarrollo continuo de herramientas de IA promete una recopilación de datos más precisa y eficiente en la investigación de la nutrición.
