What kind of object I should pass from DAL to BLL if I need to create custom type?

I have read many topics on stackoverflow but I still don't know what kind of object I should pass from DAL to BLL if I need to create custom type.
In DAL I have an entity:

public class Note
{
    [Key]
    public int NoteId { get; set; }

    [Required]
    [Column(TypeName = "varchar(MAX)")]
    public string Content { get; set; }

    public DateTime CreatedDate { get; set; }

    public DateTime ModifiedDate { get; set; }

    public virtual ICollection<Comment> Comments { get; set; }
}

But I need to return to BLL only: NoteId, Content and number of comments which aren't spam so in DAL I have a query:

public IEnumerable<WhatIsIt> GetNotesWithNoSpamCommentsCount()
{
    var whatIsIt = context.Notes.Select(x =>
        new WhatIsIt
        {
            NoteId = x.NoteId,
            NoteSummary = x.Content,
            NoteCommentsCount = x.Comments.Where(y => y.IsSpam == false).Count() 
        }).ToList();

    return whatIsIt;
}

What kind of object is it which I return - is it Data Access Object or Model or Data Transfer Object or Business Object or something else?
